Talk about method acting. During the filming of their big fight scene in Bride Wars, it seems Kate Hudson and Anne Hathway got a little carried away. “We were really tired, and I had this big rock on my finger. I whacked Annie in the face so hard,” Kate admitted on the Rachael Ray show yesterday. “She was like, 'No, no, keep going' because she was so into it. Two hours later, she’s sitting in the back of a car with an ice pack on her face. I was so bad. I really clocked her.” Ouch. Remind us never to get on Kate’s bad side!
