Did Jenner enjoy 1 Night with Paris? The world may never know. In 2008, he was photographed getting close with his ex's frenemy in Sin City on New Year's Eve. That's hot. They look like they're in the midst of a steamy kiss, but he denied locking lips with the heiress/reality star/DJ/singer. "I've never made out with Paris Hilton, so that's false," he declared. We'll take him at his word, since whatever happens in Vegas stays in Vegas.
