Get ready to drool! These not-so-famous family members of big celebrities are super hot. In many cases they might even be sexier than their famous kin.

For instance, did you know that Zac Efron has a gorgeous brother who's also pretty smart? And did you know that supermodel Gisele Bündchen has more cute sisters that look like her? Yes, there are more stunners in their families for you to ogle at.

You'll be blown away by these stars and their family members who clearly got lucky when it comes to their genes.

15  Eric Lively – Brother of Blake Lively

Blake Lively is the gorgeous actor who became a mega starlet thanks to her role on the popular TV show, Gossip Girl. Her brother Eric seems to be just as gorgeous as she is! He has the same beautiful blue eyes as his sister that's for sure. Eric Lively is obviously a model, just look at him. He's been part of campaigns for big names such as Levi's, Tommy Hilfiger and Abercrombie & Fitch. He's an actor too, though he might not be as famous as Blake. He has starred on both the big screen, such as in American Pie and The Butterfly Effect 2, and the small screen, such as in 24 and The L Word.

14 Dylan and Hopper Penn – Children of Robin Wright and Sean Penn

These kids came from some good genes and it really shows. People, quite rightly, think that Dylan is the spitting image of her beautiful mother and Hopper is a dead ringer for his handsome dad. Dylan, aged 24, has acted and modelled. She did a Gap campaign, starred in the film Elvis & Nixon. He was also in one of Nick Jonas' music videos. 22-year-old Hopper Penn is an actor and has roles in the soon-to-be-released movies, The Last Face, starring Charlize Theron, and War Machine, starring Brad Pitt.

13 Eve and Jordan Hewson – Daughters of Bono

These beauties are the daughters of U2 frontman, Bono, and activist/businesswoman, Ali Hewson. Eve Hewson, aged 24, is an up-and-coming actor who already has a few decent roles under her belt. She currently plays a nurse on The Knick, a TV drama directed by Steven Soderbergh, starring Clive Owen. Eve's older sister Jordan, aged 26, seems to be less interested in showbiz. She is a student at Columbia University and works for a charitable organisation called Global Citizen. Jordan is dating somebody that you might recognize though, Vine star Jérôme Jarre.

12 Pippa Middleton – Sister of Kate Middleton

Pippa Middleton garnered just as much attention as her sister Kate on the day she wedded Prince William. The world couldn't get enough of her hot bod in that Sarah Burton dress. The Prince's sister-in-law is an author and works for her parents' party-planning company. But the public are more interested in the socialite's personal life. The sister of the Duchess of Cambridge is always making the headlines - we are always in the know as to where she is in the world, what she's up to and who she's dating.

11 Peter Nyong'o – Brother of Lupita Nyong'o

Lupita Nyong'o shot to fame, in recent years, thanks to her first feature film role in 12 Years a Slave, for which she won an Academy Award in the Best Supporting Actress category. There's no arguing that she's a stunner, and her little brother whom we saw at the 2014 Oscars is quite the looker too. At the awards show he managed to get himself front and center in the infamous Ellen Degeneres selfie, upstaging his famous sister who's there in the background. Peter is set to play a small part in Tom Ford's 2016 film Nocturnal Animals. He might just be on his way to having a career like his sister's.

10 Mónica Cruz – Sister of Penélope Cruz

Vicky Christina Barcelona actor, Penélope Cruz, is arguably one of the most beautiful women on earth. The same could be said for her younger sister, Mónica, who pretty much looks like her twin. Mónica Cruz started her career as a dancer but ended up in a starring role on a Spanish TV show called Un Paso Adelante, which is supposedly similar in its premise to the American TV show Fame. In 2011 she was also cast as a stand-in for her sister on Pirates of the Caribbean: On Stranger Tides because Penélope was pregnant at the time.

9  Brandi Glenn Cyrus- Sister of Miley Cyrus

Brandi Glenn Cyrus, aged 28, is the half-sister of famous songstress, Miley Cyrus, and step-daugther of Billy Ray Cyrus. You'll recognize her if you're familiar with Hannah Montana as she made an appearance alongside her sister on the Disney TV show back in the day. The pretty TV and film actor has also been seen on the red carpet with her famous family on many occasions. Miley has two other maternal half-siblings, Baxter Neal Helson and Trish Cyrus, and two full siblings, Braison and Noah Lindsey. That's a big family!

8 Damon Wayans, Jr. - Son of Damon Wayans, Sr.

Damon Wayans, Jr. is the son of My Wife and Kids actor, Damon Wayans, Sr. The 33-year-old comes from a family of successful actors, comedians, directors and screenwriters so of course Wayans, Jr. is in the biz too. This handsome devil played the character Coach alongside Zooey Deschanel in the TV comedy series, New Girl. He's also had roles in the TV show, Happy Endings, and movies, Let's Be Cops, and Big Hero 6. He represents a younger generation of Wayans that we can gush over.

7  Alexander Watson- Brother of Emma Watson

We love Emma Watson. We grew up with her when she played Hermione Granger in the Harry Potter franchise and now she has taken on another role in the public eye as an advocate for women's rights. She's also a beaut obviously. Her brother Alexander Watson, whom we've seen on the red carpet with Emma, is mighty good-looking too. He's got the whole chiseled and dapper thing going on. Alex was born in Paris but spent most of his life in London. He's an actor and a model, who took part in a Burberry campaign alongside his sister in 2010. He was also in the first two Harry Potter movies as an extra.

6 Lily Collins- Daughter of Phil Collins

The 26-year-old model/actor is the daughter of iconic musician Phil Collins. And boy is she pretty! Just look at those amazing eyebrows! Lily Collins first appeared on TV when she was just two years old in the show Growing Pains. When she was younger she also wrote for popular teen magazines such as Elle Girl and Teen Vogue. She has since starred in many big movies such as, The Blind Side, with Sandra Bullock, Mirror Mirror, with Julia Roberts and Love, Rosie, in which she was the lead. She's gorgeous and has done really well for herself!

5 Georgia May Jagger- Daughter of Mick Jagger and Jerry Hall

The painfully beautiful Georgia May Jagger is a top model just like her mom was. She obviously gets her looks from her mother, Jerry Hall, and not her rock star dad, Mick Jagger, then again he was quite the sex symbol in his heyday. Since signing with Independent Models in 2008 (which is now TESS Management) she has modeled for some huge names in the fashion industry from Chanel to Vivienne Westwood. Brits will recognize her as the gorgeous girl in the ads for Rimmel London urging us to “Get the London Look!”

4 Jansen Panettiere – Brother of Hayden Panettiere

We know the lovely Hayden Panettiere from her roles in hit shows like Heroes and Nashville. Her 21-year-old brother Jansen is an actor too, although he is obviously much lesser-known. You have to admit he is very cute, the kind of cute you would imagine tweens would go for. His career got going with roles in Nickelodeon and Disney Channel movies. Since then Jansen has starred in a couple better known movies such as, The Perfect Game, and The Secrets of Jonathan Sperry.

3  Joshua Alba- Brother of Jessica Alba

I don't think you could get any hotter than these two. They're like BAM! We're beautiful. We've known of Jessica's sexiness for a while now, she was named FHM's Sexiest Woman In The World back in 2007, not that that really counts as any sort of validation. Anyway, her brother Joshua Alba, aged 33, is equally as sexy. He's an actor too. He starred alongside his famous sis in the sci-fi series, Dark Angel. He's also had some small roles on the big screen but nothing major.

2 Dylan Efron – Brother of Zac Efron

OMG there are two hot Efrons! Girls went crazy when Zac posted a super hot topless picture of his brother on Instagram last year. The 23-year-old younger brother of Zac Efron, Dylan, might even be more eligible than the movie star. That's because he's smart AND pretty. He's a noted alumnus of Cal Poly having received an award for his outstanding work on the final project of his economics degree. Dylan has attended red carpet events with his brother in the past. He also caught the public's attention when he wrote a funny poem about Zac back in the day.

1 Patricia Bündchen - Twin sister of Gisele Bündchen

Brazilian beauty Gisele Bündchen is soo hot. She's a Victoria's Secret model for Christ's sake! But did you know that she has a twin sister? They aren't identical but Gisele's twin sister, who is also her spokeswoman, clearly got some of the good family genes too. In fact, Gisele has more cute sisters. There are five Bündchen sisters in total: Gisele, Graziela, Raquel, Gabriela and Rafaela. Don't they all have beautiful names? Gisele and Rafaela have also been papped in the past looking sexy on the beach, wearing bikinis and frolicking in the ocean.
