Tallulah Willis strips for body dysmorphia confession

Bruce Willis and Demi Moore's youngest daughter Tallulah has stripped off on camera during a video chat about her battle with body dysmorphic disorder.

Tallulah Willis, 20, starts the clip fully dressed, and eventually strips down to just her underwear while she talks about her troubles, revealing she was diagnosed with the condition as a teenager.

Willis claims she deliberately dressed provocatively and starved herself to stay thin.

In the footage shot for Stylelikeu.com, she says, "I struggled a lot when I was younger... I'm diagnosed with body dysmorphia... (I was) reading those stupid f***ing tabloids when I was like 13 and feeling like I was ugly... It was just a conviction... That made me dress like I was showing off my boobs and my butt and showing off those things that I was getting attention for... It took me until a year ago (to get better)... I was trapped in this body... and I hated that I was sexy... I started starving myself and losing a bunch of weight and I got down to like 95 pounds... When I lost my curves and when my boobs shrivelled up into like nothing and I had no shape. I was just saggy skin everywhere... It put me in even more of a cage."

Willis' confession comes just weeks after her elder sister Scout was pictured walking around New York City topless as part of a campaign against Instagram.com's no nudity policy.
