Mariah Carey has fueled reports of a romance with rapper/actor Nick Cannon, after the pair was spotted partying together in Las Vegas earlier this week. The "Touch My Body" hitmaker is rumored to have hooked up with Cannon after he starred in a music video for Carey's new album E=MC2.

And the couple sparked further speculation about their close relationship after they flew in to Sin City with a group of pals on Monday night, to celebrate rapper Da Brat's birthday at club Prive, according to a celebrity blog.
