Kim Stewart and Tommy Lee at 'Rock for the Cure'

Last night, stars and socialites joined forces for Nevada Cancer Institute's sixth annual Rock for the Cure' fund-raising gala at the Mandalay Bay Events Center in Las Vegas. On this celebrity-studded evening, more than $15 million was raised for the research, treatment and education of cancer. Celebrities in attendance included Rod Stewart, Howie Mandel, Paris Hilton, Criss Angel, Sylvester Stallone, Tommy Lee, Kimberly Stewart, Sean Stewart, Larry King, Miss USA Rachel Smith and Miss Universe Riyo Mori.

Kimberly Stewart and Tommy Lee flew in with Rod Stewart on his private jet for the occasion and sat front and center for his performance before sneaking backstage where they got very romantic.

Gross!
