On Saturday at the Encore Beach Club in Las Vegas, Maksim Chmerkovskiy was photographed kissing fellow professional dancer Peta Murgatroyd, who took home the mirror ball trophy with Donald Driver last week.
That wasn't the only time the hard-bodied pair and rumored couple were spotted together in Sin City. Witnesses have seen them together all over Vegas, and the dancers appeared to be quite cozy on the East Coast recently, as well.
At the opening of Chmerkovskiy's new dance studio in Connecticut on May 23, the pair stood arm-in-arm while he whispered in her ear.
And it seems they weren't discussing how to pronounce each other's last names.
"She's had a crush on him for a long time," a source tells PEOPLE. "They are really great together. And he is very happy."
"It's early but I think this will last," adds another source. "They're a good match, a good couple. She says they're not dating but they are. Everyone knows it."
Still, at the debut of the Dance With Me studio (which Maks opened with his brother Val and fellow pro Tony Dovolani), both danced around questions about the relationship.
"I'm here to support Maksim," was all Murgatroyd would say. Chmerkovskiy wouldn't directly address the nature of their relationship either.
"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," he told PEOPLE. "It's very intimate and personal."
Sure looks like it!
