Well, what do we have here? Why, it's a slight Tricia Helfer nipple slip. The Battlestar Galactica baddie / hottie, one-time Canada's Next Top Model host, and former model attended the Spike TV 2007 Scream Awards the other night in a very tight dress, that almost had her nipple popping right out. She was lucky, though, and caught it before it escaped completely.
More Tricia Helfer pictures after the jump.
