Brody Jenner denies kissing Paris Hilton

US reality star Brody Jenner has denied claims that he kissed Paris Hilton at a New Year party.

The model, who features in MTV's The Hills, insisted that he would not ruin his friendship with Hilton by trying to initiate a romance.

"I've never made out with Paris Hilton, so that's false," Jenner told People.com. "False rumours!

"I swear to God I've never kissed Paris ever in my life. 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."

The rumours started when Hilton was spotted kissing a man dressed in a grey T-shirt and baseball hat at Las Vegas's Lax nightclub. Jenner was snapped partying with Hilton later that night, wearing clothes which were similar in appearance.
