Hot Bodies

Jen Selter -- fitness model turned ass Internet sensation -- tells TMZ Sports ... she LOVES when famous athletes and celebs reach out to her about her butt 'cause "it makes me feel special in a way."

Selter and her bulbous derriere were hittin' the streets of NYC when we talked about how her 'donk has exploded on Instagram ... with more than 2.5 million followers ... many of whom are bigtime stars.

"It's cool when talent reaches out to me ... 'cause it's like, I feel special in a way."

Also included in this clip:

-- How many squats Jen does per day
-- Who's got the best butt in Hollywood

The end.

This is WhatsApp co-founder Jan Koum in Spain with his girlfriend ... celebrating Facebook's $19 BILLION purchase of his company, and his 38th birthday.

The girl whose ass Robin Thicke grabbed after the VMAs last year hasn't given up hope on a relationship -- she tells TMZ, she still wants to go out on a date with the singer ... especially now that he's separated from his wife.

As we reported, Robin and his wife Paula Patton announced they were separating today after 9 years of marriage.

It's unclear if the infamous ass grab photo is partly to blame for the split -- but 20-year-old blonde butt-grabbee Lana Scolaro is grateful for the chance to get back in there.

She says she regrets making out with him, but tells us, "I'd love to grab a drink with him if he asked."

Here's Michael Sam at the NFL Combine in Indianapolis today ... clearly excited at his prospects of playing professional football.

Go get 'em, Mike.

Nicole Murphy and the chicks from "Hollywood Exes" found a way to make the Hawaiian coastline even more luscious ... with a very hot yoga session on the water.

The exes -- Nicole, Andrea Kelly, Sheree Fletcher, Mayte Garcia and new cast member Shanna Moakler -- traded yoga pants for bikinis ... balancing on all four in the water on paddleboards.

Alex Morgan ain't the only chick on the U.S. National Soccer Team with a super hot body ... and Sydney Leroux is making sure Sports Illustrated knows it!!

Leroux -- who was part of the 2012 gold-medal winning Olympic team -- has been on a bikini photo posting tear ever since S.I. started to push the new Swimsuit Edition, featuring Morgan.

The pics ... they're good.

To be fair, Leroux's physique hasn't been totally ignored by the media ... she WAS featured in a semi-nude pic in ESPN's 2013 "Body Issue."

And get this ... there were rumors Sydney was dating 49ers QB Colin Kaepernick -- but neither side ever confirmed.

Too bad ... for him.

You might know Natasha Oakley's name, but we guarantee you will appreciate the hard work she puts in ... 365 days a year.

And if you don't, we have only 4 words: GET ON THE TRAIN!

"Sports Illustrated" swimsuit model Chrissy Teigen isn't the selfish type -- telling TMZ, she doesn't care if her husband John Legend ogles at other hot women ... in fact, she loves it.

28-year-old Chrissy was out signing copies of the new "SI" swimsuit issue last night when we asked what she'd think if she caught John looking at the other ladies in the magazine.

Not only did Chrissy say she'd be into it ... she tells us, "We're pretty open to that kind of thing."

Michelle Rodriguez and supermodel Cara Delevingne are acknowledging the obvious -- they're the hottest lesbian couple in the universe -- and to prove it they ate out last night.

Michelle and Cara were photographed leaving a London restaurant together, looking very coupley.

And to make it official -- before their date, Michelle told The Mirror they're an item, saying, "It's going really well. She's so cool. When we started hanging out, I just thought she was awesome, and we have the best time together."

35-year-old Michelle and 21-year-old Cara have been all over each other for 6 weeks now -- starting last month with a drunken makeout session courtside at a Knicks game -- so nothing fishy about this hookup.

What makes it even more spectacular is that she's walking around in skintight leather pants.

Mind you baby Eric made his debut at 6 lbs 7 oz.

So ... Danica Patrick's exposed nipple is hanging out on a Sports Illustrated website.

The racy pic of the NASCAR driver is featured in a "Throwback Thursday" photo gallery on S.I.'s "Swim Daily" website ... which features a "selfie" style photo shoot of Danica from 2008.

We called S.I. to find out if it was a mistake ... or one of those intentional "nipples are artsy" sort of things ... but so far, we haven't heard back.

Julianne caught some So. Cal. rays with Washington Capitals center Brooks Laich. With photogs in plain sight they clearly wanted to make a statement as they walked with her teeny tiny dogs.

It's not like Ryan Seacrest will be heartbroken. He's moved on with another hot chick, who apparently is cool that he sees other people as well. In other words, don't feel sorry for him.

The woman who was targeted by Justin Bieber fans for kissing their idol in his music video has gotten her revenge ... double barrel style.

19-year-old Cailin Russo is now a model who just took these pictures -- shot in the same style as 18-year-old pseudo-naked reality star runway model Kendall Jenner. The M.O. -- I'm topless but I'm really not.

And Cailin's got 1 very important person in her arsenal:

-- Ted Emmons, a very famous photog

It makes you want to party under the stars.

Erin Andrews took a break from being yelled at by NFL superstars to remind you ... she's actually in pretty good shape.

Andrews and L.A. Kings star Jarret Stoll are on a little couples retreat at the moment -- and decided to spice things up with a stand-up paddle board session.

Not as exciting as getting screamed at by Richard Sherman ... but still, impressive.

Farrah Abraham is a porn hypocrite ...she CLAIMS she's not a porn star and is fighting the release of a sequel to her first flick but she's privately hounding porn producers to ante up a fortune in XXX royalties.

Farrah's first film -- "Backdoor Teen Mom" -- was released a year ago, yet it's still a top seller. TMZ has learned Farrah repeatedly called Vivid Entertainment last month for her quarterly royalty check. We found out Vivid wired her $93,927.72 for the last quarter of 2013.

We're told Farrah has received more than that amount from Vivid for previous quarters.

What's more ... Farrah got in the high 6 figures to shoot the flick.

As you may know ... she's been on a soapbox recently, proclaiming she's a mother and an author but not a porn star.

As for the sequel ... she can forget about it. We know she signed away all of her rights to videos Vivid might want to make from the original footage with James Deen. As a matter of fact, a Vivid source says "Expect a third one."

Word of advice to NBA players ... wrap it up TIGHT for All-Star weekend -- 'cause the gold-diggers are heading to New Orleans IN DROVES ... so says Mannie Fresh, one of the most powerful guys in rap.

Mannie -- who'll be judging a rap contest in the Big Easy this weekend -- tells TMZ Sports, "It's going down. There's gonna be a lot of chicks lookin' to get theirs ... ogling salaries."

He's right ... and one of the spots the wallet-chasers are sure to hit up is The Maison -- where Manny and Portland Trailblazers stud Damian Lillard are judging the "4-Bar Friday" freestyle rap contest.

FYI -- Lillard created the "4-Bar Friday" challenge on social media ... where people post videos of themselves trying to spit 4 lines of a rap.

Tons of NBA stars have posted their best "4-Bar Friday" attempts online in the past ... including LeBron James, Paul George, Harrison Barnes, Draymond Green, and even Damian himself.

No word if all those superstars are hittin' up the party -- but Manny says one thing's for sure ... "There will be a lot of people with a lot of money."
