Yowza! Marc Jacobs is definitely easy on the eyes.

The mega-successful 48-year-old designer flaunted his tight and sexy body while on the beach in St. Barths with ex boyfriend Lorenzo Martone.

Martone recently opened up to Dirty magazine about monogamy. He told the mag:

“I do [believe monogamy is possible]. However my longest relationship was only 2 and a half years. A lot of couples I know that have been together for 15 or 20 years have healthy open relationships. I often wonder if that influences a relationship’s longevity."

Although Martone and Jacobs ended their relationship in April 2010, seems like they're still BFFs.

Looks like Russell Brand and Katy Perry aren't roasting chestnuts together on an open fire this holiday season. The two spent Christmas apart after a "massive fight", according to Us Weekly.

Perry, 27, was originally going to fly her family to London to be with Russell's family, however she reportedly changed her plans ... and decided to spend her vacation in Hawaii.

A source close to the couple tells the mag:

"They had a massive fight. She was like, 'F**k you. I'm going to do my own thing.' Russell replied, 'Fine, f**k you too.'"

Yikes! Divorce rumors have been swirling since November, however the two superstars have denied they're having problems. The source adds:

"They haven't split up just yet, but things are not good. The fighting is getting worse."

The twosome tied the knot in October 2010. Could they be heading for a split in 2012? Looks like the ball may drop anytime.

Katie Holmes must have been going nonstop for the holidays. She looks pooped!

Tom Cruise's wifey, sporting a fresh face, was anxious to get to her Beverly Hills gym to work off those excess holiday pounds. We'll admit, even without makeup, Katie looks fab! Suri's mom just celebrated her 33rd birthday last week in New York.

Now that her hubby's movie Mission: Impossible - Ghost Protocol is out in theaters and raking in the dough ... let's hope she'll slow down.

Love the Uggs by the way, Katie!

Who knew that while Alessandra Ambrosio was strutting her stuff down the runway in the annual Victoria's Secret holiday fashion show, she was actually pregnant!

The supermodel will welcome her second child in 2012 with fiancé, California businessman Jamie Mazur, her rep confirms to Us Weekly. The pair also have a daughter Anja, 3.

Ambrosio said in a statement:

"Family is the most important thing for me and I'm thrilled to be adding to the family. I'm fortunate to have a loving and supportive family. It's a blessing that it will soon be growing."

The Brazilian stunner is four months along, but does not yet know the gender of her baby.

Is this what Santa brought the Affleck girls for Christmas?

Taking advantage of their time off from school, Violet, 6, and Seraphina, 2, set up shop in their Brentwood neighborhood, selling refreshing lemonade at 50 cents a pop from a fancy red stand, on Tuesday afternoon.

Proud parents Jennifer Garner, who's heavily pregnant with baby No.3, and Ben Affleck stood watch as their girls worked throughout the day to earn a bit of their own dough by selling drinks to friends and family.

Considering their A-list 'rents are worth millions combined, we think it's awesome the kids are still willing to learn the value of a hard-earned buck.

Ben even asked a few photogs to buy drinks from his girls, and of course, they happily obliged!

She may have enough dough to never have to do laundry again, but down-to-earth superstar Miley Cyrus still takes pleasure in the day-to-day tasks!

The former Disney star, along with her older sis Brandi and a gal pal, took the opportunity to pose for an impromptu photo shoot while taking care of some dirty laundry at an LA-area laundromat, on Tuesday afternoon.

Brandi Tweeted this caption with the pix:

“Just hangin at the laundromat with @mileycyrus and Denika Doll ... It may look like a photoshoot, but we were legit doing laundry."

Meanwhile, Cyrus‘s upcoming film comedy LOL looked like it was headed straight for DVD, but it's finally been given a release date. The flick, about a girl who loses her virginity, talks about sex incessantly, smokes marijuana (Bob Miley's specialty!), makes out with a girlfriend and accidentally reveals her Brazilian bikini wax to her mom (played by Demi Moore), will hit theaters next year.

Jonathan Cheban has found the perfect way to enjoy the holidays ... cruising along Miami Beach with a stunning bikini babe.

The Spin Crowd star, and Kim Kardashian's BFF, has been taking heat for his tumultuous relationship with Kim's ex Kris Humphries on the reality show Kim And Kourtney Take New York.

On a recent episode, Humphries called Cheban "gay" and immediately after the episode aired, reports began circulating that the jewelry designer would be taking legal action against the basketball star in a $5 million lawsuit. However, Cheban has admitted that a lawsuit would not be taking place afterall.

Sounds like a relaxing vacation in the Miami sun is just the ticket!
