Los Angeles, Jan 8 (IANS): Actress Vanessa Hudgens had put on weight and cut her hair for her role in "Gimme Shelter", and says the look of the character made her feel like a "complete disaster".

The 25-year-old, who played the role of a homeless pregnant teenager in the film, said that she was not herself when she came back from the shoot, reports contactmusic.com.

"I didn't really know who I was. Vanessa was gone. I came home and I was a complete disaster," Bang Showbiz quoted Hudgens as saying.

The actress cut her hair for the film as well.

"My best friend is still so concerned about me when she thinks about that day because I was just a bit of a mess. I wasn't really comfortable in social situations and my self-esteem was super low because I had no hair and I had put on all this weight, so physically I didn't feel attractive. And I was single," she added.

"Gimme Shelter" revolves around a pregnant teenager who runs away from her abusive mother to find her real father.
