Hot Bodies

Leonardo DiCaprio is clearly enjoying his single status and partied it up on a yacht with a bunch of hot bikini babes in Australia over the holiday weekend.

Along with all the sexy chicks -- some of whom were topless -- the 38-year-old "Django Unchained" star also hung out with his wingmen Jonah Hill and Lukas Haas.

Up until around two months ago, DiCaprio was dating Victoria's Secret supermodel Erin Heatherton.

Facebook founder Mark Zuckerberg is white hot -- exposing his burly man chest while vacationing in Maui.

Zuck wasn't shy about sharing his topless physique while taking his wife Priscilla Chan out for a private surf lesson.

See, there is something $14 billion can't buy.

Kobe Bryant made an extremely rare appearance on the Sunset Strip for New Year's Eve -- and he did it with his sometimes estranged wife Vanessa Bryant.

Kobe and Vanessa -- both dressed to the nines -- sure looked like things are back on for 2013 as they walked out of BOA Steakhouse.

We asked the Black Mamba what he's doing to stay on top of his game -- and he answered, "lot of hard work."

Here's the thing -- was he talking about basketball ... or Vanessa?

Her year-old divorce petition is still filed, but our sources say it looks like they're working things out ... again ... for now.

Olympic legend Michael Phelps has broken up with girlfriend Megan Rossee ... TMZ has learned.

Look at the photo above, then read that sentence again.

According to our sources, Phelps felt the relationship wasn't going anywhere, so he decided to end it so he could pursue other options.

And apparently in the world of Michael Phelps, those options are somehow better than this.

Former "Hills" star Audrina Patridge is selling her bikini-clad body (again) -- stripping down for a smoking hot 2013 swimsuit calendar -- and TMZ has every month's picture.

Trust us, it's awesome. In fact, it has everything you could ever hope for ...

Audrina's boobs ... check.
Audrina's boobs oiled up ... check.
Audrina's boobs by a pool ... check.
Audrina's boobs on a chair ... check.
Audrina squeezing a dog in her boobs ... check.

MMA fighter Nick Newell might only have one arm ... but he's definitely got plenty of balls ... telling TMZ he's more than capable of fighting in the Octagon -- even if UFC prez Dana White isn't convinced he can pull it off.

Nick's already the undefeated belt holder in the Xtreme Fighting Championship, but tells us he'd kill to cross over to UFC -- however, White's expressed reservations because, as he puts it ... "It's hard to fight with two arms, you know what I mean?"

Nick's response to Dana is honestly, brutal -- "I've won by arm bar, rear naked choke, guillotine, heel hook, TKO and knockout. In 9 pro fights I have never been out struck."

He adds, "If you have followed this sport, or know anything about it, you would be able to see that I'm amongst its elite. Just because I'm not in the UFC doesn't mean I wouldn't beat most of the guys in there."

Your move Dana.

But soft! What light through yonder window breaks? It's Jennifer Aniston, who continued her ridiculously hot Mexico vacation yesterday ... looking pensive in a sexy bikini and an exotic red sarong (the thing wrapped around her waist).

As we reported, Jennifer and her tatted-up fiance Justin Theroux have been kicking it in Cabo San Lucas over Christmas, and things just keep heating up.

Still unclear if Jennifer's pregnant -- but if you're wondering what it's like to get held up in Mexico ... just ask her boobs.

Joanna Krupa's hysterical attempt to stand-up paddleboard in Miami proves even though she's well-equipped to float ... she's far from seaworthy. Still hot as sin, though.

Jessica Simpson's new baby has hit the milk-dispensing JACKPOT -- and lucky for us, the singer's already giving out a sneak preview of the goods.

Jessica -- who's currently on vacation in Hawaii with her fiance and baby #1 -- just posted the ample photo on Twitter ... with the caption "Fun in the sun." And we have to agree.

Jessica Simpson and Eric Johnson are going to extremes to hide something -- like every inch of their bodies during their family vaca in Hawaii.

We've already seen Jessica covering up on the beach since announcing her pregnancy ... but during a Christmas Eve stroll on the beach even Eric was cloaked from head-to-toe while carrying baby Maxwell.

Far as we know ... Eric doesn't have a deal to drop lbs on Weight Watchers.

The only Simpson not in undercover mode these days is Ashlee Simpson ... who proudly showed off her bikini bum.

Russell Simmons could teach Halle Berry a thing or two about breaking up. He's on such good terms with ex-wife Kimora Lee, he kicked it with her AND new GF Hana Nitsche Wednesday on the beach in St. Barths.

Simmons and Kimora Lee divorced in 2009 ... but they stayed unusually and refreshingly close post-split ... sometimes vacationing together with their respective SOs.

There's no question Russell can pull some impressive ass -- but we gotta ask ...

Jessica Simpson raked in millions of dollars from Weight Watchers to drop her baby lbs -- just in time to put it all back on with a brand new fetus! Busiest womb in Hollywood, folks.

Jessica Simpson is hiding something -- because the newly pregnant singer just hit the beach in Hawaii ... wearing an enormous green cover-up thing.

Just one day after announcing her new bun in the oven, Jessica went out for a waterfront stroll today with her fiance Eric Johnson ... and her rapidly-forming fetus.

This will be Jessica's second child after she gave birth to her daughter Maxwell in May.

Who knew? Justin Theroux is tatted neck to toe.

The pics were snapped in Cabo San Lucas, Mexico over the weekend. Jennifer Aniston, who at 43 still looks mighty fine, and Justin were catching some rays when he stood up and revealed a back tat that looks kinda ... Asian-y.

Jennifer makes a yearly pilgrimage to Cabo around XMAS time and usually George Clooney follows suit -- this time with lucky Stacy Keibler. And Rande Gerber and Cindy Crawford always make the trek as well.

FYI --There are reports circulating that Jennifer is pregnant. If she's really pregnant, Jessica Simpson has been doing it seriously wrong.

Just two days before she made her big announcement, a secretly pregnant Jessica Simpson took her fetus on a Christmas Eve shopping spree ... and showed off her growing baby bump.

While wearing an animal print tunic-thingy, Jessica hit up a Target store in Hawaii on Sunday to stock up on wrapping paper and all sorts of other competitively priced stuff.

It's unclear how far along she is, but it's gotta be early ... considering you can BARELY see the bulge in her midsection.

Side Note: Her legs look great!

Stephanie Seymour's butt is unavailable at the moment -- as it's currently on vacation in St. Barts.

If you would like to leave a message for the butt, please do so at the beep.
