Brody Jenner smooching Paris Hilton is a "false rumor." The Hills star has adamantly denied kissing the socialite at a New Year's Eve party in Vegas.

"I've never made out with Paris Hilton so that's false. False rumors!" the reality TV star says at the Stoli Hotel Opening Wednesday.

The rumors that he and Hilton had locked lips started when some vague photos of the celebutante seemingly kissing a guy in a gray shirt and baseball hat appeared on the Internet. Another picture shows Hilton hanging out with Jenner, who is wearing a similar outfit.

"I swear to God I've never kissed Paris ever in my life," he denies saying they are just close friends. "We're friends but never, never ever, ever was it a romantic thing, ever. I would love to see proof of us kissing because that's never happened. I swear."

And while he denies Paris, Jenner coyly admits someone else. "I'm not allowed to talk about it but yes, I do have a girlfriend and no, her name is not Lauren Conrad."
