Maksim Chmerkovskiy and Meryl Davis have both denied that they're dating but their insane chemistry on "Dancing With the Stars" has a lot of people wondering if something romantic is going on. Chmerkovskiy and Davis won Season 18 of the ABC show and it seems like their personal lives is starting to overshadow their dancing victory.

According to Hollywood Life, an eyewitness spotted the duo dining together at TAO restaurant in downtown New York City on May 22. The onlooker told the site that Chmerkovskiy and Davis were "very close" and "doting" all night.

"He was really attentive to her and they were talking very close to each other in the corner of the skybox at TAO before dinner," the eyewitness said. "He kept kissing her on the forehead and was really doting."

"He had his arm around her a lot and they were smiling the entire time," another onlooker added. "He's a really touchy feely guy and they have great chemistry."

In a previous report by Life & Style magazine, a source on the set of "Dancing With the Stars" said that the professional dancer and the Olympic ice skater were spotted kissing backstage.

"It's even more intense [off screen]," a source said. "There were no cameras on them, but Maks was spotted kissing her and hugging her. They seem super close, and it is definitely not just for the cameras. Everyone on set has noticed their chemistry."

"They only talk with each other at the show and are really touchy and flirty," the source added. "He is always talking about her great body and has his hands all over her, even when the cameras are off."

Even though the world is convinced there's something the two are a couple, Chmerkovskiy's ex-fiancé Karina Smirnoff (who is also a pro dancer on "Dancing With the Stars") told US Weekly that it's "great acting."

"When you're on the dance floor... you want to create that story, you want to create something where people believe that what you demonstrated was real," she said. "And [Maks and Meryl] were able to do that."
