They absolutely live and breathe sport, follow strict diets, and train every day, sometimes twice a day or even more, all to be the best possible athlete they can be. We see them at their championship-winning best (that's you, Tom Brady), and we see them at their 10-game losing streak worst. But if we take a little step back, leave the stadiums and glimpse into their personal lives, wow, there's some serious selfie gold just waiting to be uncovered.
If it weren't for the fascinating yet addicting technology-dominated world that we currently call home, we'd never see these athletes' questionable bedroom or travel photos, and we'd never have had the blessing of knowing that LeBron James gets pedicures, Cristiano Ronaldo wears face masks, Patrick Kane gets loose on Cinco de Mayo, and Usain Bolt likes to fool around.
20 Usain Bolt is quick, in more ways than one
Jamaican-born Usain Bolt might be the fastest man to ever walk the face of the earth, however, that doesn't mean that he's the most faithful, not for a second. The eight-time Olympic gold medal has notched up a few mistresses over the journey, with one example being the Brazilian student named Jady Duarte pictured here.
19 David Beckham and his mystery drink
While we'll never actually know without a shadow of a doubt whether the former soccer star is sipping on a cold vanilla milkshake or a freshly-made health-conscious smoothie, we're still enjoying have a chuckle. It turns out that celebs are also prone to awkward eating and drinking selfies - who knew?
18 Nate Robinson getting acquainted with his dentist
Making an appearance as the face behind our next obscure athlete selfie is none other than Nate Robinson, a basketball point guard who's floated between the New York Knicks, Chicago Bulls, Denver Nuggets, LA Clippers, Boston Celtics, Oklahoma City Thunder, Golden State Warriors, and New Orleans Pelicans. Keep for photos to the court, Nate, not the dentist's office.
17 Cristiano Ronaldo and his strict beauty regime
He's an icon of soccer, he's an icon of Portugal, and he's even at various stages been an icon of sports modelling. For that reason, you'd expect that Juventus superstar Cristiano Ronaldo keeps a rather strict beauty routine - and you'd be right. Here he is in all his glory, using a face mask and body mud to keep his skin glowing.
16 It's all forehead for the Undertaker and Kurt Angle
You know when grandma grabs your phone and tries to take a selfie, only to have her forehead take up 80% of the frame? It's an all-too-familiar experience for us, and we feel that the Undertaker and Kurt Angle are getting a little too close to that awkward forehead zone. Try again, boys.
15 LeBron James needs to take care of his feet
Just because he's one of the most infamous basketballers of all time, it doesn't mean that LA Lakers star LeBron James avoids taking care of his feet. For athletes, pedicures aren't a luxury, they're a necessity - helpful for avoiding nasty infection, calluses, and all that other uncomfortable stuff. We do feel for the lady though, considering that James sports size 15 feet!
14 The Kobe Bryant and Lionel Messi combo
Who doesn't love a good old cross-sport collaboration selfie, right? On the right, let us draw your attention to arguably the greatest soccers player of all time, Lionel Messi, looking like he's ready to model. As for his buddy Kobe Bryant in the background, however, well, you be the judge.
13 Is that baby Conor McGregor?!
Looking like he's just woken up on the wrong side of the bed, this Conor McGregor selfie doesn't quite live up the shredded, usually clothing-absent selfies we've become accustomed to seeing the Irishman snap outside of the ring. What do we think, people - could that be baby Conor in the background?
12 The Rock feeling generous
While these days, Dwayne Johnson is one of the highest-paid Hollywood actors, starting in action flick after action flick, his background is, and will always be, sport. Before he sold out stadiums as WWF's The Rock, he was actually trying his hand to become a professional football player.
11 Patrick Kane on a day he'd like to forget
Folks, we're jumping over to Madison, Wisconsin in 2012, where Chicago Blackhawks right winger Patrick Kane had 'a little too much fun', so to speak. While celebrating Cinco de Mayo, Kane reportedly had a few too many brewskies under his belt, which caused him to lash out at passerbys. This photo is certainly one he'd like to forget.
10 Neymar and... Niall?
What's better than superstars from two different sports coming together for a quick selfie? Superstars from two different industries altogether, that's what. Combined, the Brazillian soccer star and former One Direction singer Niall Horan have close to 150 million followers on social media.
9 Sydney Leroux with a few too many chins
It's hard to debate the fact that Sydney Leroux is one of the most impressive female soccer players in the world, however, that doesn't mean that she's above taking unflattering bed selfies. We've all been there and done that, no doubt, but it's not often you see an Olympic gold medalist rocking the double chin.
8 Tom Brady and Giselle are perfection
With six Super Bowl trophies from nine appearances (which is the most of any player in NFL history, by the way), Tom Brady's resume is stacked. Hit better half, Gisele Bundchen, is one of the highest-paid models of the 21st century. As a couple, they're as close as you can get to perfection, and we can't stop gawking with jealousy.
7 Ronda Rousey, you missed a spot
Long before the days when Ronda Rousey was kicking but in the squared circle with the WWE, she was an MMA fighter for the UFC, and a seriously impressive one. As you'd expect, that nature of work doesn't come without its physical risks, and this awkward selfie is one perfect example of that.
6 Steph Curry getting animated
Sometimes, your Snapchat stories can be screenshotted at the worst possible moment. Thankfully, the NBA legend, Stef Curry isn't doing anything too untoward in this live video, however, it's still not his best angle, that's for sure. Whatever he's talking about, it looks as if he's getting rather intense about the subject.
5 There's a reason they call Floyd Mayweather 'Money'
When your nickname is nothing more than 'Money', you can go ahead and buy as many chunky gold necklaces as your heart desires. Admittedly, this low-angled selfie doesn't give Floyd the most glamorous of appearances, but it's certainly a way for him to show of his bling. Care to share around any of that coin, Floyd?
4 LeBron James needs some hydration tips
We all love a refreshing drink once in a while, especially after a workout - or in LeBron James' case, after carrying his team on his shoulders on the basketball court. Ask any doctor, however, and they'll attest that water is the best hydration method, not Sprite, as LeBron is trying to aggressively convey.
3 Jo-Wilfried Tsonga and Gael Monfils living the high life
While this pair might not boast the same list of accolades as a Federer or Nadal, Jo-Wilfried Tsonga and Gael Monfils are undoubtedly still up there with the elite of their generation, especially in their home country of France. They seem to be having a great time aboard their privately chartered jet, and we're all kinds of jealous.
2 Athletes from both Koreas unite for a selfie
It's not often that the northern of the two Koreas is in the news for something positive, however, this photo is a shining light that proves otherwise. Back in 2018, despite their differences, the North and the South joined forces to compete in the Winter Olympics, rocking a blue and white Korean unification flag.
1 Zlatan Ibrahimovic being Zlatan Ibrahimovic
It doesn't matter if you're an LA Galaxy fan or not, it's hard to past the sheer brilliance of Zlatan Ibrahimovic. But it's not just his fancy footwork that turns heads, it's his comical, arrogant, laid-back personality. With that in mind, seeing him snapping selfies while chillin' on a private jet should come as no surprise at all.
