A Maxim party would not be a Maxim party without a bevy of reality stars on hand. On Saturday, young Hollywood's favorite party people - including the entire cast of The Hills - ventured to Miami Florida's The Raleigh to revel in their own hotness.

Stephanie Pratt was the only lady in the bunch to opt for a burst of color, wearing a sequined blue skirt with a midriff-baring black top. The skirt is rad, as is thee slouchy clutch, but is this a look you'd feel comfortable posing and partying in all night long? Also, I thought she'd been arrested on suspicion of DUI - what's she doing at a party?

Kristin Cavallari, meanwhile, wore a little black strapless dress. Perhaps she didn't want to upstage her castmates for once. Same went for Audrina Patridge.

The most exciting of the crew might have actually been Lo Bosworth, who wore a silky Alexander Wang halter dress with off-the-shoulder sleeves.

Last weekend may have been about the Saints and the Colts, but Jets heartthrob Mark Sanchez still managed to steal one show in Miami.

Our snowbird spy says the quarterback had lots of ladies fawning over him at a Maxim bash at the Raleigh Hotel on Saturday, but Sanchez had eyes for only one gal: "The Hills" star Kristin Cavallari.

"He was definitely all about Kristin," the source dishes. "They even left together at the end of the night."
