kate beckinsaleKate Beckinsale has reportedly asked for a body double for a shower scene in her new film Whiteout because she’s worried her bum is too wobbly to be exposed to the camera.

In the comic-book adaptation, Kate plays a US marshal in Antarctica who has three days to solve a murder before the continent shuts down for its long winter - but Kate refused to strip in the line of duty.

A source told the Daily Mail: “Kate has a terrible self-image. She thinks she is fat and she is always complaining how certain outfits make her bottom look big. Of course, the reality is that she has the most amazing body.

“The script called for her character to be filmed nude in a shower, focusing in on her bottom and thighs. Kate insisted on a double being hired.

“She was quite open on the set about not liking her body and said she particularly loathed her bottom and was not comfortable baring it.”

“She said she couldn’t face the thought of seeing her butt up on a big screen.”

A last minute call was put out this week to find the stand-in ahead of the scenes being shot this week. The casting call requested a 5ft 8 brunette, weighing just under 9st - but the source added that it’ll be up to Kate in the end: “She will have the final veto over who stands in for her.”
