Tallulah Willis ''struggled'' with body dysmorphia when she was younger.

The 20-year-old blogger - who is the youngest daughter of former Hollywood couple Bruce Willis and Demi Moore - was diagnosed with the condition when she was 13, meaning she has a distorted view of her own appearance, and claims she always felt ''ugly'' because of gossip written about her family.

Stripping to her underwear for a StyleLikeU video interview, she said: ''I struggled a lot when I was younger.

''Like I'm diagnosed with body dysmorphia with reading those stupid f***ing tabloids when I was like 13 and feeling like I was ugly, like always. I believed the strangers more than the people who loved me because why would the people who love me be honest?''

Tallulah admits she began dressing more provocatively in ''denim short shorts and push-up bras'' and lost a worrying amount of weight, but her physical transformation left her feeling worse than ever.

She added: ''That made me start to dress showing off my boobs and my butt and those things that I was getting attention for.

''I was trapped in this body. 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. It put me in even more of a cage.''
