Paris Hilton El Nuevo Boy Toy ... Muy Guapo

Paris Hilton picked up something new in Mexico ... and he's a total stud.

Paris is hanging in Tulum this week with a mystery man. Here's what we know about him so far -- he likes walks on the beach in his jeans ... and rolling around with Paris. Not necessarily in that order.

Looks like P is putting the breakup with whatshisname behind her. What's that saying about the best way to get over one guy?

Paris is a believer.

Britney Spears' Boyfriend You Want A Hot Body? You Better Work, Bitch!

Britney Spears' BF, Sam Ashgari, barely broke a sweat lifting weights at Muscle Beach, but the same might not go for people breezing through photos of his intense workout.

Sam, who appeared in Brit's "Slumber Party" video, hit the famed open-air weight room in Venice Friday afternoon with his actor pal, Sam Jones III.

Hard to tell who's more ripped from the photos, but it looks like both dudes easily ate 100 chin-ups for lunch.

If the sun's out, these buns will always follow suit.

KJ and Tyga are down at Joe Francis' famed estate in Punta Mita, Mexico ... and lounging by the pool. Kylie didn't leave much to the imagination Tuesday as she flaunted some ass-tastic swimwear.

Two things:
1. She's gonna need more sunscreen
2. Tyga's hands never looked so small.

Maria Sharapova Like A Rock Even During Tennis Suspension

Maria Sharapova might be in the middle of her 15 month suspension for doping but she's still dope.

Maria enjoyed a little R&R on the island of Lanai over the New Year and, judging by her rock hard body in that tiny black bikini, she's been keeping up with her tennis training.

She returns to the court in April, so better get that R&R in while she still can.

In related news, the swimwear managed to stay on even while she splashed around with a pal.

Can't win 'em all, guys.

Don McLean This Chick's Not My American Pie! Even If She Wants To Be

The 22-year-old model's been blowing up her page with pics of her and Don together for the holidays, with captions like "Aloha & Merry Christmas from my Donny and I" ... all while wearing a fat rock on her ring finger.

Paris does Don's social media. You'll recall his wife filed for divorce earlier this year.

So bye bye, Paris. No Mrs. American Pie here ... so they say.
