'Dancing' pros Maks and Peta get cozy in Vegas

Peta Murgatroyd has a new trophy. And a new boyfriend.

The pro, who won on the recent Dancing With the Stars season with NFL star Donald Driver, was caught kissing fellow pro and resident bad boy Maks Chmerkovskiy in Las Vegas last weekend.

Peta, with cigarette in hand(!), locked lips on the dance floor (where else) at XS nightclub with Maks (also a cig in hand!). Peta wore a red dress; Maks sported a black T-shirt and jeans. He wrapped his arm around her and the two got very cozy.

According to People, this was not the first time the hardbodies bonded. On May 26, they shared a smooch at the Encore Beach Club in Las Vegas. And a few days earlier, they were whispering in each other's ears at the opening of his new dance studio in Connecticut.

But neither is going public about the romance. "I try to keep certain things private just because - what's the politically correct way of saying it? It's none of anybody's business. It's very intimate and personal," Maks said. Peta also danced around the topic, saying only, "I'm here to support Maksim."

Maks has dated show mates before. He was engaged to Karina Smirnoff for eight months in 2009.
