Derek Hough is reportedly putting the moves on Lauren Conrad despite denying reports that the two are dating.

The Dancing with the Stars professional partner partied with Conrad in the back room of Los Angeles' Trousdale Lounge, dancing and kissing on the dance floor, People reported Tuesday.

"It was obvious there was a lot of chemistry between the two. She was very smitten," a source who saw the pair together told People, adding that Hough had his arm around Conrad's waist.

"Neither seemed embarrassed about kissing in public."

Hough was reportedly hanging out with fellow Dancing with the Stars professional Mark Ballas, while the former The Hills and Laguna Beach star had her friend and fellow former co-star Lo Bosworth at her side.
