The dance continues.
Maksim Chmerkovskiy and Meryl Davis brought their ballroom sizzle to Tao Downtown in New York on Thursday night, celebrating their Dancing with the Stars victory with dance pros Val Chmerkovskiy, Tony Dovolani and Jenna Johnson.
“He was pretty touchy-feely with her, but if you know Maks he’s touchy-feely with a lot of people,” an observer says. “Are they a couple? It’s hard to say. He had his arm around her waist and was giving her lots of kisses on the forehead.”
While Chmerkovskiy, 34, and Davis, 27, have been coy about their relationship – even as they gush about each other – those close to them believe the fireworks are all just an illusion.
“There is a clear, loving chemistry between them,” Dancing host Tom Bergeron tells PEOPLE. “So many people say that this is a sexual chemistry. Maybe I’m naïve, but I don’t see it that way.”
