This is sooo funny, and we're totally on Team Christina!

A source at the Sundance Film Festival tells X17online exclusively that Christina Milian had an incredibly uncomfortable (yet hilarious) run-in on Saturday night with Nick Cannon and Mariah Carey.

Christina (who dated Nick from 2002 to 2005) was at a T-Mobile party hanging out with some friends when Nick and Mariah started walking toward her. As she saw them approaching, the singer turned her back and totally snubbed her ex-boyfriend, and when Nick spoke to her, Christina "acted as if she didn't even hear him." Our source added, "You could tell Mariah was in a very awkward position."

Awkward indeed!
