Justin Timberlake must have hoped he’d seen the Sexy Back of his ex Cameron Diaz. So he didn’t look too happy when the pair were reunited for Press interviews at the same Beverly Hills hotel. Justin and Cam both do voices for animation movie Shrek III.

When they were doe-eyed lovers working together must have seemed a cute idea. But Justin had a face like thunder as he left the meeting at the Four Seasons.

Well I dont know why they are so mad at each other it must be a celebrity thing.
