Okay, I have no idea why the hell Bai Ling is at Cannes. Then again, I don't know why Paris Hilton is there either. At least, unlike Paris, though, Bai Ling is doing something productive with her time in Cannes. And what is she doing? Why, slipping the nipple, what else. Yes, it's a completely gratuitous Bai Ling nipple slip, but aren't gratuitous nipple slips always the best?
Update: I've figured out why Bai Ling is in Cannes. If you look past her breasts, and exposed nipple, you may notice some posters for Shanghai Baby. I guess that's a movie she's in. Now, the question still remains, why is Bai Ling in a movie?
