Kristen Stewart Black and Blue Dress Pictures on Tonight Show

Kristen Stewart continued her promotional rounds for Breaking Dawn Part 1 with a stop by The Tonight Show With Jay Leno yesterday. Kristen slipped on her second minidress of the day, a black and blue Monique Lhuillier, after being spotted in a casual plaid shirt outside of Jimmy Kimmel Live earlier in the evening. Talk with Jay turned to her newest project Snow White and the Hunstman, which she's been working on in London.

Kristen shared details about a recent fight scene she filmed with costar Chris Hemsworth where she actually punched Chris in the face when she "was supposed to miss him by this much." Kristen went on to explain with excitement, "It made such a sound! Girls, if you’ve ever wondered if it works — it works! I mean, it literally spun him right around. It was crazy.” The punch wasn't the cause of her current hand injury though, it was apparently due to the dwarves. Kristen said, "those pesky little creatures. I broke my thumb on one of them. Actually, I didn’t break it. It was a really bad ligament tear.”
