The former That '70s Show actor has been photographed out with Kelly on several occasions in recent weeks, and the pair was allegedly seen kissing and dancing together during a night out at West Hollywood's Greystone Manor Supperclub last weekend (18Mar12).
A source told UsMagazine.com, ""They were kissing and grinding,"" adding, ""I wouldn't say they're boyfriend and girlfriend, but he's started ignoring calls from some of his other girls.""
But Valderrama, who split from singer/actress Demi Lovato in January (12), brushed off the reports during a Los Angeles radio interview with Ryan Seacrest on Thursday (22Mar12).
When asked about the love claims, Valderrama adopted his cartoon voice for his Disney Junior show Handy Manny and said, ""Well, Minka Kelly and Wilmer Valderrama have been friends for a long time and that's all there is to it.""
The actor, who has voiced the Hispanic handyman character since 2006, has also previously dated Mandy Moore and Lindsay Lohan. Kelly, the star of the failed TV revamp of Charlie's Angels, parted ways with baseball ace Derek Jeter last year (11).
