Celebrity Butts

She may be from Florida, but Ariana Grande put her butt on the line for the Seattle Seahawks last night.

Mercedes Javid paid homage to Denise Richards' character in 'Wild Things' by squeezing into a micro thong swimsuit for a very soapy and public car wash/cry-for-attention.

M.J. shamelessly posed while putting a shine on her Volkswagen SUV in L.A. -- even though the city's in the midst of severe drought.

She's been very open about her dramatic weight loss over the last year, which she chalks up to a healthy appetite for sex.

Still ... washing a car is a pain in the ass.

Cuba Gooding Jr. flashed his American spirit right along with his ass crack ... during Labor Day weekend.

Cuba sported a Paul Revere hat and stars and stripes board shorts while showing off the dark side of the moon on the beach in Malibu

Rihanna struck a few fantastic poses -- standing, sitting and kneeling -- on a standup paddle board in Italy over the weekend.

Wiz Khalifa's number one album is his victory, but Amber Rose is sharing the spoils with the world.

To celebrate Wiz's "Blacc Hollywood" topping the Billboard album charts, Rose posted a video of herself on Instagram twerking away ... captioning it, "In honor of my Hubby's #1 Album #blacchollywood #AssDrop."

Call him Shaquille O'NEILL ... 'cause the retired NBA Big Man hit the ocean hard in Florida this week ... with his super hot girlfriend by his side -- and TMZ Sports has the pics.

Shaq and Laticia Rolle were spotted in Cocoa Beach, FL on Tuesday by Louis Barr Photography ... splashin' around on the beach like a couple of teenagers.

FYI -- Shaq and Laticia have been hangin' out a lot this summer ... probably safe to say they're dating.

Jennifer Lopez and Iggy Azalea teamed up for a remix ... which is totally irrelevant when compared to the amazing photo that has ass aficionados stacking the vintage model against the new one.

So, who would you rather -- dream about? 'Cause realistically, ya got no shot.

Nicki Minaj's "Anaconda" music video is filled with ass -- but now, thanks to the glorious power of the Internet (and some editing software) ... it's also got a lot of gas.

A comedy duo out of South Africa named Derick Watts and the Sunday Blues released the flatulent remix late Tuesday night.

The concept might be is definitely juvenile ... but we dare you to watch it without cracking a smile.

For those who haven't seen Nicki's original -- SHAME ON YOU!!

It's a battle of the booty!

Here's Jennifer Lopez showing off her 45-year-old bulbous backside (left) posing with 24-year-old Iggy Azalea's down-under donk (right) in a photo promoting their upcoming remix together.

Fashion model Megan Hawkins just earned her street cred ... but it may hamper her career ... she took a bullet apparently meant for Suge Knight at Chris Brown's VMA party ... and took it in the butt.

The 5'11" blonde-haired, blue-eyed model posted photos -- showing her in a hospital bed and using a walker to get around -- with the comment, "my ass took a 9mm and I'm keeping it as a souvenir."

Megan -- who's just 19 -- was one of 3 people shot inside 1Oak nightclub early Sunday morning.

Here's an unspoiled view of Megan pre-wound. Enjoy.

Dr. Gerard Butler displayed his vast knowledge of the female anatomy ... by administering a mammogram in a public parking lot.

Butler was in Malibu this week with an unidentified smoke show when he started exploring inside her bikini balloons -- following up with a tush grab.

With the surge of big-booty stars like Nicki Minaj, Iggy Azalea and Kim Kardashian it's no surprise famous people are taking to the web to put their backsides on blast!

NBA superstar J.R. Smith had one hell of an entourage last night -- rollin' into a NYC hotel with a group of BADONKS who would give Nicki Minaj a run for her money.

Seriously ... so much ass.

Here, in all its glory, is supermodel Adriana Lima's message to all her fellow countrymen still licking their wounds from that humiliating World Cup loss to Germany.

It's pretty simple -- ultimately, Brazil always comes out on top. Or, in this case ... bottom.

We know ... Lima's Victoria's Secret shoot has nothing to do with soccer. But who's complaining?

Kim Kardashian stepped out of her New York City apartment Monday afternoon with a slew of fans waiting to catch a glimpse of her ... including Officer Staresalot over here.

But really ... he's doing NOTHING wrong. In fact, he's supposed to be watching her ... and he is.

And the gold medal for "Camera Whoring with Your Ass Out" goes to ... Brittny Gastineau -- and this video proves it beyond a shadow of a doubt.

Kim Kardashian's pal appeared to be several drinks in when she poured herself all over a bar at the Fontainebleau Hotel in Miami this weekend -- and slowly undressed while blatantly mugging for paparazzi.

The most awesome part of this video is not Brittny's ass ... but the fact everyone around her is totally ignoring her.

You know how this ends, right? With Brittny passed out, looking like she's auditioning for "Weekend at Bernie's."
