Kristen Stewart accidentally punched her Snow White and the Huntsman co-star Chris Hemsworth in the face.
The 21-year-old actress is currently shooting the fantasy movie and left the Hollywood hunk with a black eye and a "big lump on his nose" after a fight scene went wrong.
In an appearance
on The Tonight Show with Jay Leno, Kristen - who is playing the titular character - revealed: "Girls, if you've ever wondered if it works, it works! I was supposed to miss him but I basically knocked him right out of his close-up."
The Twilight Saga star - who has been pictured with scraped and bruised knuckles this week - also revealed she won the sought after part after a "really intense, four-hour" meeting with director Catherine Hardwick.
Kristen - who is dating Robert Pattinson - added: "I hadn't read the book when I accepted the part. It was crazy."
