Maksim Chmerkovskiy and fellow "Dancing with the Stars" pro dancer Peta Murgatroyd need to play coy no more on the nature of their relationship. They were caught on camera kissing during a night outing in Las Vegas over the weekend.

The "DWTS" dancers were spotted locking lips on the dance floor at XS nightclub in Las Vegas, so TMZ reported. Peta wore a red dress, while Maxim donned a black t-shirt and denims. He wrapped his arm around the blonde beauty and leaned close to her.

According to PEOPLE, this was not the first time the couple were pictured kissing. On Saturday, May 26, they shared a smooch at the Encore Beach Club in Las Vegas. A few days earlier, they were said getting cozy at the opening of his new dance studio in Connecticut.

Both of them dodged the question about the rumor. "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," Maxim said. Peta, meanwhile, stated, "I'm here to support Maksim."

A source, meanwhile, said, "She's had a crush on him for a long time. They are really great together. And he is very happy." Another insider stated, "It's early but I think this will last. They're a good match, a good couple. She says they're not dating but they are. Everyone knows it."
