"Dancing with the Stars" pros Maksim Chmerkovskiy and Peta Murgatroyd provided more evidence of a romantic relationship Saturday when they were photographed kissing each other at the Encore Beach Club in Las Vegas.  A source tells People magazine Peta's "had a crush" on Maks for a long time, adding, "They are really great together. And he is very happy."

Another source confirms the romantic relationship, telling the magazine, "They're a good match, a good couple. [Peta] says they're not dating but they are.  Everyone knows it."

Maks and Peta were also spotted together last week at the opening of his new dance studio in Connecticut.  "I'm here to support Maksim" was all Peta would say about the relationship.  Maks was a bit more direct, telling the magazine, "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."
