It's clearly "Lip Lock Wednesday" here at PopEater. We already brought you Adam Lambert's in concert "tongue dive," and now here's the new 'Black Swan' trailer, featuring a brief-but-intense moment between Natalie Portman and Mila Kunis.

So do they hate each other? Love each other? Kill each other? We're dying to find out.
