Hot Bodies

Kendall Jenner doesn't need a bra ... because her own father fully supports her breasts.

Sources close to Bruce Jenner tell TMZ, he 100% backs his 18-year-old daughter's decision Tuesday to expose her nipples on Instagram. As far as he's concerned, she's a fashion model ... and that's what fashion models do.

Soon after Kendall posted the pic for her 7 million followers, Bruce began defending his daughter ... saying she's a "wonderful kid and a great daughter" ... and insisting he's proud of her no matter what she does.

Just so we're all clear ... Kendall turned 18 on November 3rd. We're proud of her too.

After only 16 days since her 18th birthday … Kendall Jenner decided to give the world a glimpse of her nipples … leaving everyone wondering ... what took so long?

Now here's the question ... does it all end with nipples, or will Kendall walk the path forged by her older sister, with the helping **** of Ray J?

And while we're at it ... we gotta ask ...

We don't know how far Carmen Electra was planning to run ... but thankfully she remembered to do some amazingly sexy stretches beforehand.

Most importantly, she did it in front of cameras. Thanks, flexibility!

Wayne Gretzky's unbelievably beautiful daughter Paulina nearly bit the dust when her sweater caught fire at a bar -- which means we almost lost the hottest celebrity spawn on planet Earth.

Or the second hottest ... according to one of our mental staffers.

Here's the reportedly 6'1" American made super model Karlie Kloss (21) towering over the reportedly 5'11" Brazilian bombshell -- and mother of two -- Gisele Bundchen (33) at an awards ceremony in New York City last night.

Here's Kate Upton ... basically naked ... with some strategically placed body paint.

You're welcome.

Kate got all painted up for a Sports Illustrated photo shoot -- in the footage, Kate's trying to recreate one of the mag's most famous Swimsuit Edition covers.

We think she nailed it.

"I definitely feel naked," Kate said during the shoot ... "Because I am."

Kate said the artists took a particularly long time to paint on the necklace on her boob area ... yeah, can't imagine why.

Never wanting to miss Upper Body Day, 65-pound Justin Bieber attempted a pull-up in Brazil on Tuesday -- and nearly burst every capillary in his face.

"Thor" star Jaimie Alexander blew everyone's mind by wearing a dress that barely covered her lady parts to the premiere ... a move we applaud.

Particularly for its attention to side-boobage!

So ... Jaimie Alexander won the "Thor" premiere last night.

The 29-year-old actress -- who plays Lady Sif in the movie -- rolled up to the El Capitan Theater in Hollywood wearing a dress that BARELY covered her lady junk.

Asgard ... meet Ass-guard.

Justin Bieber is kicking himself right now ... because ex-girlfriend Selena Gomez and her perfect 21-year-old ass just hit Miami Beach in this bikini.

Beats stripper ass any day of the week.

Kim Kardashian started an ass-selfie trend ... 'cause after she shared her bikini-wedgie with the world ... ANOTHER wanna-butt celeb is following suit.

This time, the chick showing off her donk is Mercedes "MJ" Javid from "Shahs of Sunset."

It's definitely a change of pace from Kim ... and pro surfer Anastasia Ashley, who beat MJ to the punch with a butt-selfie last week.

Butt-selfies -- sometimes they're not all they're cracked up to be.

Rihanna's sexy vacation pics sent our minds off to the magical Land of Hypotheticals -- where you can ponder just how much danger you'd expose yourself to ... in order to get with RiRi.

Of course we'd never have a shot in hell of being near her -- so this game's all we got.

Here's Rihanna ... bent over a pole while wearing a tiny bikini ... in a series of hot poolside photos she just took while hanging out in Greece.

There's not really much more to say ... so, we'll just go with "Ef̱charistó̱" ... which, we're told, means "thank you" in Greek.

Hours before Pauly D knocked up Amanda Markert, they were both raging at a crazy pool party in Vegas ... and TMZ has several pics of the boozy scene right before the drunken conception.

The two met at the legendary Rehab pool party at the Hard Rock Hotel in the summer of 2012 ... Pauly was working the DJ booth and Amanda was partying her face off in a smokin' hot bikini.

At one point during the party, Amanda somehow got on stage (probably because she's hot) ... and sprayed down the crowd with a bottle of champagne. Later she was seen double-fisting novelty-sized cocktails.

Soon after that, she got some one-on-one time with Pauly -- and 9 months later she gave birth to his daughter. A true love story ...

But the connection they had in Vegas stayed in Vegas ... 'cause now Pauly and Amanda HATE each other's guts and are at war over custody and child support.

Vegas baby, VEGAS!!!

She's been naked for Playboy ... and donned itsy-bitsy bikinis for Sports Illustrated ... so it's no wonder Stephanie Seymour wasn't shy when it came to trying on lingerie in Italy yesterday.

The 45-year-old model grabbed some racy outfits while shopping at Agent Provocateur in Milan with her 66-year-old husband Peter Brant ... and tried them on right in front of the store window. It was awesome.

FYI -- Peter Brant is a paper mogul who happens to be a frickin' BILLIONAIRE!!!

So, good for him ... and good for her.
