Natalie Portman has cleared up rumors suggesting she stripped for a swimming scene in new film Your Highness, insisting it was too cold for her to take a dip naked.

The Black Swan star appears naked from behind in the titillating scene - but she has revealed a body double was the one baring her behind.

She explains, "There's one shot that's me and the shot of her diving into the water is a body double, because I didn't wanna go in the water - it was really, really cold."

The scene hit the headlines recently after producers were forced to cover the naked body double up for the film's trailer. A black bikini outfit was digitally added to the clip.
