Nick Cannon & Rihanna???

Here is the rumor as reported at BET.com:
NICK CANNON "RI"-UPS
Remember, last week, we reported that Christina Milian was rumored to be dating producer/rapper Dre, of the production duo Cool & Dre. Well, Nick Cannon isn’t wasting anytime either. Apparently, he’s been seeing the sexy Carribean songstress, Rihanna, says US Weekly. Now, the interesting thing here is that Christina and Rihanna are actually labelmates. So don’t expect any collaborations from the two of them in the near future.
Oh yeah, before the question even comes up, she's legal. Rihanna is 18 and Nick is 25.
