Hot Bodies

Justin Bieber ripped off all his clothes, except for his Calvin Klein boxers, during Tuesday night's "Fashion Rocks" event in Brooklyn -- but flashing his bod and ego nearly backfired.

Biebs was on stage with model Lara Stone to introduce Rita Ora, when he decided to strip down. You can hear boos start to rain down at first, but the more naked he got ... the more the screaming chicks started to win out.

Justin tweeted after the show, "Grandma always said kill 'em with kindness...and then strip on live national tv. Lol."

Thanks for nothing, Granny.

Khloe Kardashian's been crushing it in the gym ... drawing ever closer to the ultimate goal -- because on the Kardashian family tree there can only be one ass to rule them all.

Everyone, including Khloe, knows Kim's been the standard bearer ... the most famous butt in the family

So, here it is -- Kim vs. Khloe, kakes vs. kakes. Khloe actually answered ... but do you agree?

The Miss Bumbum Brazil contestants have the most awesome way to celebrate reaching one million votes in the competition -- they've released a lingerie photoshoot to say thanks.

Online voting will determine 15 finalists from the 27 chicks vying for this year's title ... and the finalists will duke it out in Sao Paulo in November.

This year's contestants include a Megan Fox look-alike, a pair of twins, and a 39-year-old woman, who is apparently the oldest contestant they've ever had.

Paris Hilton is not so cool that she can't chow down on Subway ... she just thinks she's too cool to be SEEN with a Subway sandwich.

Everyone's favorite leggy socialite was spotted Monday hitting up the popular sandwich shop in New York City, but as soon as she walked out ... and realized the paps had seen her ... she tried (unsuccessfully) to slip the sub behind her clutch.

Either she wants to promote fashion over food, or she is still holding on to her Carl's Jr. days. It's gotta be the latter ... for us.

A couple of ice cream cone pasties were all that stood between Miley's nipples and her crew as they cruised into an Alexander Wang after party.

Miley rolled in to the event with Tyga, Kendall and Kylie Jenner and others -- but everyone else was boring and, y'know .. fully clothed.

Shia LaBeouf did his best impression of a teenager on the high school wrestling team Saturday in Studio City ... rolling around town in a killer pair of spandex.

The 28-year-old actor and his girlfriend Mia Goth hit the town for a lunch date and we're guessing he just finished some sort of aerobic exercise. Or maybe he's just incredibly fashion forward in a way us mortals just don't comprehend.

In case the tank top looks familiar ... it appears to be the same one Shia wore during his extremely dramatic ice bucket challenge.

Tight.

Ajay Rochester -- who hosted Australia's version of "The Biggest Loser" -- just had 1.5 Liters of fat sucked out of her body ... but first, she bellied up to a 1,000 calorie breakfast of bacon, eggs and hash browns.

Ajay hit up Dr. Aaron Rollins Friday at Elite Body Sculpture in Bev Hills, and got something called an Airsculpt Laser Lipo -- a fancy name for precision fat sucking. We're told Ajay was 100% awake for the procedure -- no needles, no cutting, no stitches -- while the doc targeted her chin and arms.

Ajay says her ultimate goal is rocking sleeveless dresses and tops -- not that she was thinking about that when breakfast was served.

It's back-to-school season which means Summer is officially over -- but before you go and buy pumpkin flavored EVERYTHING... take a magical trip through the last few months and soak up all the sexiest pics to hit social media.

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

NBA all-star Blake Griffin has been on beaches all over the world ... so he's definitely seen both sides of the great debate -- board shorts or skin-tight Speedos?

So, now with no further delay -- Blake reveals his fave style to package Mr. Bo Dangles!

Sure, she put a hurtin' on a heavy bag in that new Under Armour ad -- but how would Gisele do in a real fight with fellow supermodel pugilist Adriana Lima?? She'd get her perfectly sculpted ass kicked.

At least according to actual boxing champ Peter "Kid Chocolate" Quillin.

By now you've seen the Gisele ad -- and it's impressive -- but she can't hold a candle to Lima ... who's been boxing for years and even trained with Manny Pacquaio.

"Seeing [Lima] hit the pads, I expect her to do better in the ring than Gisele," Quillin says ... noting her form, her power and her precision.

"Hitting the pads is different than hitting the bag ... it's harder. You have to have more direction with the pads. But you really never know what kind of fight someone has until they step in the ring."

But Quillin says he was definitely impressed with Gisele too ... especially when it came to her physique.

Gisele Bundchen has gone from simply being a knockout ... to trying to do the knocking out in a gym. It's all part of a new ad campaign -- and for perhaps the first time in history -- there is NOT unanimous joy over Gisele bouncing around in a sports bra!

The times they are a changing.

Rita Ora slipped into the sexiest body suit since Catwoman ... and took it for a stroll around London Wednesday.

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.
