Grainy photos of the pair apparently kissing on an LA club dancefloor were published on X17. An eyewitness told the gossip site, "They were dancing close for a while and being all touchy-feely and finally Chris leaned into her. She put her head on his shoulder and they started kissing!"
But a rep for Nicole tells TMZ, "There is absolutely no truth to the ridiculous story ... The photos that have surfaced are of old friends who were trying to talk at a very loud club. They were not kissing."
Former Pussycat Doll Nicole is dating Formula One racer Lewis Hamilton. Chris reportedly split from model Karreuche Tran recently.
