VIDEO: Kate Upton Injured Her The Other Woman Co-Star Filming Sex Scene

Nikolaj Coster-Waldau stopped by Chelsea Lately Thursday night to talk about a major battle wound he got on set while filming The Other Woman — and apparently, it was all co-star Kate Upton’s fault.

Coster-Waldau said the two were filming a sex scene in which Upton had to spank him with a whip. She might have gotten a little carried away — because the bruise on his butt is pretty terrifying.

Take a look in the video above.
