Stars In Heat

It seems like only yesterday, Kourtney Kardashian was self-delivering baby Mason from her lady parts in front of the reality show cameras ... and look at him now!

No seriously, try to look at him ... bet you didn't even realize there was a child in this picture.

If Selena Gomez was trying to find a way to make Justin Bieber REGRET breaking up ... this hot red outfit will probably do the trick.

Gomez -- and her butt cheeks -- were hanging out in Palmdale, CA this week ... where word on the street is that she was shooting a new music video.

Muy bien.

Never say Scott Disick isn't well-adjusted ... and the best part -- he can do it all by himself!

Scott was in Mexico recently, hanging with baby mama Kourtney Kardashian, his son Mason and a bunch of friends.

We don't know if Scott went crab diving during the vacation ... but we hear they're in season.

In between making pizza and tanning, "Jerseylicious" star Filippo Giove found time to show off what his mama gave him -- BY DROPPING TROU for Playgirl and TMZ has the pics.

Filippo -- a star on the Style Network show since 2010 -- stripped down to his bday suit and posed in a variety of sexy (ish) positions for the upcoming Spring issue.

Specifically, Filippo shows off his derriere on some red satin sheets ... poses with a few strategically-placed bubbles and gets naked in a pizza shop while slathered in marinara sauce -- with only a LARGE pizza box covering his junk.

Justin Bieber turns 19 today ... so he walked down the streets of London in half his birthday suit, lamely showing off his baby abs and his ultra-cool training boxers.

The drop-crotch pants, and the Vanilla Ice fade haircut was just too cool for school. The only saving grace ... he wasn't wearing that stupid hat.

The pic was snapped after his performance, as he walked to his hotel.

Someone needs to hang this kid upside down from a balcony.

Suge, are you listening?

Good thing body checking's legal in hockey ... because Wayne Gretzky's smoking hot daughter Paulina showed off her overflowing bosom last night in L.A. ... and everyone was looking.

24-year-old Paulina's breasts made their appearance at Bootsy Bellows nightclub -- somehow strapped inside a tiny red dress.

Remind us ... what's the penalty for high-sticking?

Know why it doesn't suck to be the quarterback who lost the Super Bowl? Because hot girls will drink alcohol out of your belly button no matter what.

The photos just surfaced ... showing 49ers QB Colin Kaepernick partying on board a cruise ship in Mexico last year ... letting girls do body shots off his six pack ... and they're so awesome, we couldn't resist posting them.

More impressive ... the pics were shot BEFORE Colin replaced starting QB Alex Smith.

"Splash" -- formerly known as "Celebrity Diving" -- seems like just another reality TV show ... until you see Katherine Webb in a bathing suit.

The former Miss Alabama USA -- famous for her cameo at the BCS National Championship this year -- donned the magenta monokini earlier today while filming a show segment in L.A..

It's only been one month since Mallory Hagan won the title of Miss America 2013 ... after KILLING IT in the swimsuit competition ... and it appears she's back to eating like a normal human being again.

24-year-old Hagan was spotted rocking a pink bikini in Hawaii yesterday ... still looking incredible ... with a little more to love.

Sometimes ya just gotta let loose.

"Shahs of Sunset" star Mike Shouhed got a helping hand from his butt oiling assistant/girlfriend as he readied his hairless golden muscles for his Playgirl spread, Sunday in L.A..

While there's no official word if he is going to go full frontal or pull a Levi Johnston, with a strategically placed towel, the 34-year-old real estate stud did let most of it all hang out while prepping for the shoot.

For the good of all mankind, the gorgeous ladies did what they do best and poured all of their luscious golden lady bits into skimpy frilly lingerie -- and super high stiletto heels -- and struck some amazing poses.

There's no way this is real -- just two months after Gisele Bundchen popped out a baby girl ... the Victoria's Secret supermodel whipped her hair back and forth in Hawaii ... LOOKING LIKE THIS.

While every other new mom on the planet has been contemplating excess skin removal surgery, Gisele and her supernatural genes basked in the Hawaiian sun Thursday.

Gisele gave birth to her and Tom Brady's second child on December 5 -- a daughter named Vivian Lake Brady.

Memba when TMZ published those pics of Kate Upton in a really tiny bikini in the middle of Antarctica??? Turns out we TOTALLY SCOOPED the Sports Illustrated Swimsuit Edition's cover!!!!!

Ooops!!!

Earlier today, the super-secret cover was leaked to the Internet ... featuring Kate in the middle of the frozen antarctic tundra ... a shoot they TRIED to keep under wraps.

We published the pics back in December, right around the time they were shot -- when the temp dipped down to 35 BELOW.

But Kate braved the elements like a stud -- and it totally paid off.

And now we have another reason to look at our candid shots from the glacial "set" ... as if we really needed one.

While most of the country is freezing their asses off, former "The Hills" star Audrina Patridge warmed her sexy bones by slipping into a tiny bikini and hitting the sand with her pup in Manhattan Beach.

The 27-year-old is the perfect cure for the winter blues.

It's pretty much freezing everywhere else on the planet ... but this weekend in L.A. it was in the 70s -- and "Shahs of Sunset" star Mercedes "MJ" Javid took full advantage of the warm weather.

Not wanting to waste a moment of sunlight, Javid stepped out in her natural habitat on Sunday -- a hotel pool -- and sunned herself in a wild bikini.

Don't hate us 'cause we're beautiful.

Bar Refaeli's mouth has the power to turn a regular man into a bona fide Casanova ... 'cause that geek she sucked face with in the Go Daddy commercial says chicks have been all over his jock ever since the spot aired.

The lucky sonofabitch in the commercial is Jesse Heiman who tells TMZ his life has completely changed in the past week ... and obviously, all for the better.

"I’ve actually had guys tweet me that they wish they were me, and girls tweet me saying they wish they were Bar.”

But the interest from the ladies isn't just from the cyber variety -- Jesse explains, "I have girls run up to me and take pictures with me, tweet me for dates.”

Jesse tells us his career has also exploded ... saying, "There are lots of inquiries coming in to my agent and manager, their phone has been ringing off the hook, but they are really letting me enjoy the moment right now.”
