There must be a special force that Isaac Newton failed to discover that causes WAGs to invariably gravitate toward each other.
These sexy wives and girlfriends of athletes are constantly finding new BFFs who are also members of the athlete community.
Take for example Marisa Miller, Adriana Lima, and Selita Ebanks. They're all WAGs and they all like to hang out and go to Belvedere Vodka parties together in hot outfits.
It seems like the ladies of the sports world are in a secret club and need a special password in order to be friends, and all these ladies have been let in on the secret.
Here is a list of the sexiest sports BFFs.
Kim Kardashian and LaLa Vasquez have been BFFs for a long time. Kim was even in charge of planning LaLa's bachelorette party.
Now rumor has it that the two are looking for apartments in the same building.
Neighbor sports hottie BFFs! Overload...
In case you don't own a television set or a computer (yes I'm aware that a person of that description wouldn't be reading this...shut up), I'll go over some of Kim K.'s claims to fame.
She was originally famous for having a big butt and a sex tape with Brandy's brother, but she has somehow managed to turn that into a full-fledged media empire including several television shows, a fragrance, and a hit pop single...well a pop single at least.
She's a notorious WAG, having dated Reggie Bush, Miles Austin, and now Kris Humphries.
LaLa Vasquez (occasionally referred to as the minimal, "LaLa") was famous for annoying people on MTV for a few years.
She then quit her job to become full-time girlfriend and now wife of Carmelo Anthony.
It's got to be awkward when one BFFs boyfriend is a lot better than the other's. Girls are so catty, it has to come up at some point.
"My shoes are prettier than yours."
"Oh yeah, well my husband dropped 35 on your boyfriend last night!"
People often meet their BFFs in the workplace. Luckily for us, these two Victoria Secret models hit it off and became friends.
It wasn't taken to BFF status until they found out they were both dating athletes. That's when the half-heart necklaces came out.
Gisele, besides being one of the hottest women on the planet, is known for dating Patriots Golden Boy Tom Brady (I think that's what it says on his business card).
In an effort to prevent Tom from leaving her, Gisele continues to insist that he wear his hair in a ponytail.
"Are you sure this works? I feel stupid."
"No way baby, you look hot...trust me (menacing laugh)."
Contrary to popular belief, Lima is not married to a guy named "Who?" In fact, she is married to prolific NBA scorer Marko Jaric.
Jaric's career averages of 7.1 points and 3.6 assists are sure to get him into the Hall of Fame class of 2014.
Maybe then photographers won't ask him to get out of the shot when he goes out with Gisle, Tom, and Adriana.
These two have been friends for a long time and have been seen doing plenty of awesome BFF things like going to the beach and going out for lunch.
Not sure how many times Serena has been mistaken for Kelly's boyfriend, but it's got to get old pretty quickly.
Serena Williams dominated women's tennis for a few years but injuries and boredom have caused her to pursue other interests.
Like fashion. And long walks on the beach.
Once a member of the supergroup Destiny's Child, Kelly went on to pursue her solo career (aka Beyonce left her in the dust) and was rumored to have dated NBA player Kenyon Martin in 2010.
Now she's singing techno/disco songs with David Guetta and dressing up like a futuristic military commander when she's not hanging out with Serena.
With last names so similar, how could they not be BFFs? They also happen to be in the same British pop group, Girls Aloud. And they both happen to be WAGs.
Not sure what the conversation turns to after sports and music...maybe Kit Kats?
Cheryl Cole (aka Cheryl Tweedy) is one of the most famous WAGs in England. She married Chelsea soccer star Ashley Cole in 2006, but the couple divorced when reports came out that Ashley cheated on her.
I'll never understand these celebrities that cheat on the hottest women on Earth. I guess athletes are used to getting what they want and always want what they can't have.
Coyle has always played second-fiddle to Cheryl Cole, but she seems to prefer to be out of the spotlight.
Instead of going the traditional British WAG route of dating a soccer player, Nadine branched out to date former NFL scrub Jason Bell.
The couple announced their engagement in 2010, so maybe it's not best to have every part of your relationship published in a newspaper or on a website.
The two famous WAGs have been seen cavorting around Beverly Hills together, and even participated in an LG commercial with the slogan, "Friends. Fashion. Fabulous."
If that doesn't say BFF I don't know what does.
Eva even organized Posh's baby shower and in return Eva has been walking around in clothes from Beckham's clothing line.
Now that Longoria's divorced, I'm sure she's spending a lot of time around the Beckhams.
"Sure, Eva, you can come to dinner...again..."
Better known as Posh Spice, Victoria Beckham is arguably the most famous WAG of all time.
She was a member of the biggest girl group on the planet (for about three months) and her husband was the best soccer player on the planet for a few years.
Not sure what the connection was, but it could have had something to do with Posh's brilliant performance in Spice World.
Better known as Eva Longoria-Parker, she is known for her role in Desperate Housewives and for being shown on the sidelines more than the players during Spurs playoff games.
She probably doesn't hang around the Spurs anymore, partly for fear of bumping into her ex-BFF Erin Barry.
Nothing unites a pair of women like getting together and complaining about their husbands. There's certainly plenty of material for BFFs Evelyn Lozada and Jennifer Williams.
The basketball "wives" have had plenty to dish about their athlete "husbands" and they will continue to do so on the third season of Basketball Wives.
Really? Basketball Wives gets a third season but Love Monkey couldn't even make it through it's first? There is no justice in the world.
Lozada got on the show because she was engaged to the Shimmy-Master himself, Antoine Walker. That ended long ago, of course, and she's now poised to be a football wife.
She's engaged to the brash and outspoken Chad Ochocinco who had a reality show to find love, but soon realized that it was waiting for him all along...on an other VH1 reality show.
Jennifer Williams is the ex-wife of alien impersonator Eric Williams, and she constantly complains about how he cheated on her.
What does a fake celebrity to do to get back at him? Of course!
Take some nude photos with your cell phone and have them "leaked" on the internet. That's reality star 101.
Ciara and Rihanna are both R&B/Pop sensations that have WAG written all over them.
We all know about Rihanna's tumultuous past with blonde-haired, shirtless lunatic Chris Brown, and we're pretty sure Ciara was there to help her get her life back together.
Ciara managed to avoid WAG status for a while, but she eventually succumbed to the charms and horn-rimmed glasses of Knicks All-Star Amare Stoudemire.
The two were trying to keep their relationship under wraps for a while, but it's tough to do that in New York. Eventually Ciara was seen at the Knicks game sitting with Carmelo's wife LaLa.
What would Rihanna say?
Rihanna made the best decision of her life when she left Chris Brown (the second-best decision of her lfie was growing bangs to hide her five-head), but she quickly jumped into the arms of Dodgers outfielder Matt Kemp.
Kemp enjoyed a fruitless 2010 season while dating RiRi and the couple called it quits in late 2010.
Maybe Ciara can hook her up with a Knick.
The two Yankee WAGs have been known to go to games together to see their boys in pinstripes.
Couldn't they go to a few summer games together? This is the most clothes I've ever seen either of them wear.
The Friday Night Lights star will forever be known as the girl that tamed Derek Jeter.
That is until Jeter calls off the wedding after sleeping with every female cast member of Gossip Girl after his bachelor party.
Garcia is an actress better known for being the wife of clubhouse comic Nick Swisher. Maybe she and Kelly can help calm him down so he stops breaking the legs of helpless Japanese second basemen.
Let's see, we both like to wear bathing suits, we both date athletes, and we're both smoking hot. I know, let's be besties!
The two SI swimsuit models clearly have plenty in common, and they make for a pretty nice "girls night out".
Just as Minka Kelly has settled down Derek Jeter, Irina Shayk is famous for taming the model-dating infidelity machine Cristiano Ronaldo.
There are rumors that Shayk is pregnant, so that could either lead to Cristiano embracing his role as a daddy or catching the next flight on the Shawn Kemp express.
I guess we'll find out soon enough.
Irina's BFF was known for dating Russell Simmons (what!?) before settling down with SuperBowl MVP Aaron Rodgers.
I'm sure it led to endless football vs. football debates between Ronaldo and Rodgers.
Ok so maybe they had a falling out (no pun intended) but Tara Reid and Paris Hilton had to be included on this list.
The two "actresses" were known for partying it up in the mid-2000s and both dated famous athletes.
'Tis better to have BFF'd and lost than never to have BFF'd at all...or something like that.
Tara is known for dating Tom Brady, Jeremy Shockey, Kyle Boller, and Sergei Federov. She's also known for making horrible choices both in acting roles and in life.
One great choice she made was becoming best friends with Paris Hilton. It's the only way she could get into the club.
Hilton is another celebrity famous for no apparent reason. She was one of Cristiano Ronaldo's many conquests.
Word was that Ronaldo just couldn't handle dating a jailbird.
