Celebrities have been well trained and groomed on how to deal with the press, media, and fans. Whether they’ve been in the spotlight for fifteen years or fifteen seconds they have an agent, publicist, stylist, make up artist, hairdresser, personal shopper, and so much more. They are taught to look and act the part. When the cameras are rolling celebrities flash their million dollar smiles, wave to their fans, and try to act as down to earth as possible. However, what happens when the cameras are off? Or how about when the paparazzi aren’t watching their every move? It turns out celebrities are in fact not perfect humans, and can be down right mean when it comes to taking time out of their day for contest winners, fans, and supporters.

Some celebrities have a bad reputation when it comes to their behaviour on set, whether it be making ridiculous demands, or disrupting other co-stars. Various singers have also been pegged to have a diva personality when it comes to performing on international tours. Although these celebrities may seem like absolute sweethearts to the general public, they can be cruel and disrespectful when it comes to getting what they want. Here are the top 20 celebrities who are secretly mean people!

20 Carrie Underwood

Carrie Is America’s not so sweet heart. Carrie portrays the classic girl next door however, many people who have met her have reported differently. The American Idol winner must’ve forgotten her roots as she’s been caught acting rude and arrogant towards fans. The singer admitted she is selfish and closed off. Not only have fans complained about her behaviour, but other stars have commented on Underwood’s lack of respect for others. When the camera is on, Carrie is the sweetest gal, however, backstage is a different story. An example of this is when Carrie told Leighton Meester before presenting to “get out there and don’t **** up” at the CMA awards in 2010. When confronted about what she said Carrie replied “she’ll get over it.”

19 Julia Roberts

Julia Roberts is another star that would appear to be a compassionate, caring, and kind women. Unfortunately this is not reality. Roberts has made headlines for bullying her half sister and calling her “a fat failure.” Her sister sadly fell into a deep depression and committed suicide in 2014. Julia’s late sister Nancy admitted that Robert’s ego and fame ruined their sibling relationship. Nancy’s husband believes that Julia and her family are to blame for his wife’s death. Nancy’s husband reported he believes that Julia and her family are the most flawed in Hollywood.

18 Ariana Grande

Ariana Grande is another Nickelodeon gone wrong pop sensation. She appears to be a happy girl, however there’s different side to Ariana. Ariana’s last name fits perfectly as she truly believes she is grander than anyone else on the planet. The self-proclaimed diva has treated fans and contest winners poorly. A prime example of this occurred when two young teens got to meet Ariana. They took photos with her and then she demanded that they be deleted. After spending less than a minute with them, the teen begged to keep the photo of her, Ariana then told her security to make sure the photo was deleted. The Cab’s lead singer also added that Grande is the “most stuck up, disrespectful person in the industry.” As for the cherry on top, Grande recently said "I hate Americans, I hate America," while in a doughnut shop, all caught on tape. 

17 Justin Bieber

Justin Bieber grew up before our eyes. He was a sweet kid who seemed to truly care about his fans. Recently, Bieber has been in the news and making headlines for all the wrong reasons. From drugs, to alcohol abuse, and vandalism, Bieber can’t seem to get his act straight. The entitled pop star apparently called one of his fans a “beached whale” after she approached him in a bikini. Spectators reported that he suggested she should become a contestant on The Biggest Loser. Biebs, although it’s evident you were not taught proper manners growing up, if you don’t have something nice to say, don’t say anything at all!

16 Shia LaBeouf

From Even Stevens to motion pictures, Shia grew up in the industry and should therefore know better than to treat others as if they are beneath him. Shia, you’re still human and put your pants on one leg at a time, just like everybody else. Three teens approached Shia to get a photo and he refused, he did shake all their hands, however, it would’ve meant the world to them to have a picture with the Transformers star. Shia has made fans cry, not of happiness that is. After a man’s girlfriend tried to speak with Shia in a London restaurant, he brought her to tears. The man confronted Shia and the situation turned violent quickly. Shia told the man he could “have him killed.” Easy tiger.

15 Lindsey Lohan

Although she may have played the sweetheart in Mean Girls, Lindsey definitely knows how to play Regina George in real life. Lindsey is apparently aware of her power over people and uses it to manipulate others into getting what she wants. Lindsey is reported as being self-obsessed and selfish. Apparently the introduction of Sam Ronson into Lindsey’s life forced all of her other relationships to fall by the wayside, and she didn’t care. Lindsey’s careless demeanor can be seen in the multiple drunk driving charges and other criminal charges she has faced.

14 Jason Biggs

Jason Biggs is one of those people that feel the need to tell the world what he thinks and how he’s feeling on a regular basis. Whether he’s going off on an evil Twitter rant or dissing ex co-stars, Biggs who looks like a nice guy on the outside, is actually incredibly rude. His offside comments include dissing Tara Reid’s body and calling her a hot mess. He also took to Twitter to criticize contestants on the Bachelor based on their appearance. He went as low as to make fun of individuals with disabilities. His shallow and disrespectful remarks have left me concerned that he’s a public figure and a parent.

13 Tom Cruise

Cruise is known for his odd outbursts, strange interviews, and of course, scientology beliefs. However, he never struck fans as being mean. While interviewing with Matt Lauer for the Today Show, Cruise went as far as to criticize Brooke Shields for taking medication for her postpartum depression. To put someone down for seeking help and assistance with their mental health while going through a difficult time is unacceptable. Brooke Shield’s response was perfect as she was quoted saying “I’m going to take a wild guess and say Mr. Cruise has never suffered from postpartum depression.” That’s right Brooke, he most certainly hasn’t.

12 Vanessa Hudgens

High School Musical heartthrob Vanessa Hudgens admitted that she was mean to other girls and female fans of her former boyfriend, Zac Efron. Vanessa said she was sick of girls throwing themselves at her ex-boyfriend so she became jealous and mean. It was also reported that Vanessa was bullying co-star Selena Gomez on the set of Spring Breakers. Vanessa was taunting Gomez calling her a Disney princess who doesn’t know how to party. Selena took to twitter expressing the anxiety she was experiencing while on set for the film, and now we know why!

11 Christina Aguilera

The pop princess is making more enemies than friends in Hollywood. The powerhouse singer seems sweet and caring on the show “The Voice,” however, fellow celebrities have had some serious complaints about the star’s behaviour. Valerie Bertinelli ran into the singer and was showering her with compliments when Christina interrupted with “yeah whatever,” and proceeded to walk away. Sick of hearing how talented you are? Then step out of the spotlight Christina. Christina justifies her assertive ways as being taken for rudeness. There’s a definite difference and Aguilera has yet to figure it out.

10 Josh Duhamel

Josh Duhamel is a tall dark and handsome actor who has made our hearts skip a beat in flicks like Safe Haven, When in Rome, and Win a Date With Tad Hamilton. However, infidelity rumours hit his marriage to Fergie like a freight train in 2009. Josh was accused of sleeping with an Atlanta stripper, Nicole Forrester. Nicole passed a lie detector test, which focused on the relations she had with Josh. To add to the validity of the so-called rumour, Nicole also had texts on her phone from Josh. Once Nicole’s story was brought to the forefront, many other women stepped up claiming that they too had slept with Mr. Duhamel. Mr. not so faithful needs to be reminded that a happy wife means a happy life!

9 Naya Rivera

Naya Rivera is best known as playing the sassy cheerleader Santana on Glee. However, after acting like a total diva on set, Naya was kicked off of Glee’s season 5 finale. Not only does she expect to be treated like a queen and waited on hand and foot, she’s also been inconsiderate to co-stars. She even sparked a fight with Lea Michele who plays Rachel Berry on the show. Naya was slowing down production, demanding breaks, and was all around a nuisance to work with. Perhaps Ms. Rivera needs to be reminded that if it weren’t for Glee she wouldn’t be famous at all.

8 Kirstie Alley

Kirstie Alley appears to be a friendly woman whenever she’s interviewed on talk shows or in magazines. Unfortunately this is not the case! Kirstie took to twitter to bash one of her good friends, Leah Remini, for leaving Scientology. She went as far as to shun Leah for leaving Scientology, as did many other famous members of the church. The real life mean girl also tweeted “haha I love talking smack.” Kirstie is a bit old for high school drama, however, I suppose she had nothing better to do that attack Remini via social media platforms.

7 Cameron Diaz

Cameron Diaz is old enough to know better than to treat fans poorly, especially at a premiere for "Sex Tape," which is her own movie. Diaz has been in the business long enough to know what to expect when it comes to screaming fans, signing autographs, and walking the red carpet. When fans asked to get a photo with Diaz her response was “if I did it for you I’d have to do it for everyone,” and she proceeded to walk away. Well, that’s one way to lose your fans respect and support!

6 Beyonce

Queen B is quite possibly the most famous female celebrity. Known for her powerhouse voice, drop dead gorgeous looks, and fierce persona, Beyonce seems to have it all. Beyonce’s climb to the top did not come without stepping on some toes. When performing at the Super Bowl Beyonce surprised the crowd with a Destiny’s Child reunion. She also surprised Kelly and Michelle by turning their microphones volume lower than her own. They also had to sing one of Beyonce’s hits rather than sticking to Destiny Child tracks. Considering her career skyrocketed while Kelly and Michelle’s plateaued, could she not have let them have their moment at the Super Bowl? Guess it’s all about B!

5 Kim Kardashian

Kim has gained worldwide attention from her clothing line, reality show, various divorces, and most recently, her marriage to Kanye West. Kim made headlines for all the wrong reasons in 2014 when she refused to have a photo taken with Chris Brown’s girlfriend, Karrueche Tran. When Karrueche tried to talk to Kim she proceeded to walk away. It is possible Kim is primarily jealous of Karrueche’s natural beauty and youth, especially after publicly calling her “lowbrow.”

4 Jennifer Lopez

Jenny from the block may have forgotten her roots, as she has been far from down to earth in recent years. The singer even went as far as to insure her butt for $27 million dollars. Since her higness’s rear is so important, she demands that the only toilet seat she sits on be germ resistant and custom made for her. When planning ahead to stay at a five star hotel, Jennifer makes sure to send two pages of the food, drinks, and décor she prefers to have upon arrival. Jen also shut down J.Law when she asked her to dance at the Met Gala in 2014. Lopez’s response “no, I’m good here.”

3 Hilary Duff

Ever since her Lizzie Mcguire days Hilary has portrayed herself as America’s Sweetheart. However, even the sweetest women can have their moments. During an interview with Cosmopolitan magazine Hilary randomly dissed Chris Brown and his ex girlfriend for tweeting about their relationship. Hilary also showed her unpleasant side when she responded to criticism from Faye Dunaway regarding her role of Bonnie in “The Story of Bonnie and Clyde.” It seemed as though Duff was going to take the highroad until she stated that “I think it was unnecessary, but I might be mad if I looked like that now.” The snarky remark made Duff seem bitter and catty. Who in their right mind publicly disses an accomplished 70 year old actress?

2 Zooey Deschanel

Zooey is known in Hollywood as being quirky and dorky. However one thing that is not brought to the limelight is the fact that she’s actually really mean! Insiders have reported that Zooey treats co-workers and staff terribly on the set of her show “New Girl.” Zooey has even taken it upon herself to make up rules on set, including ending each show with a scene involving her and one other character. Her moody behaviour and ridiculous demands are beyond irritating for many people who work on the show.

1 Katherine Heigl

Katherine Heigl has always played lovable characters on television and in movies. She pulls off the sweetheart role too well! She must be a doll in real life, right? Not so much! Katherine is known to be difficult on set while filming. She has been reported as having an attitude problem and an insider who worked on the film “Life as We Know It” said the star could cost you every day of shooting. What types of disruptions does Heigl cause? She goes from complaining about her wardrobe to questioning her lines and even refusing to come out of her trailer. Apparently Heigl needs a reminder that she’s there to play an adult, not a toddler having a tantrum.
