LOS ANGELES: Rebel Wilson says she became an actress because she wanted more friends. The 36-year-old was "unusually shy" as a child so she enrolled in an acting class and it quickly helped her "find self-esteem". She told Britain's Marie Claire magazine: "I didn't become an actress because I wanted to be famous, I did it because I was so unusually shy bordering on a social disorder. "So my mother... One day she drives me to this community acting class. I was holding on to the car door and crying. She had to peel me off the car... Good on my mother for seeing I had a problem," she added. Wilson said she was "sick of not having any friends". "She might not have dealt with it in the most delicate of ways but I was sick of not having any friends. That is why the creative arts are so important for young people. You can find self-esteem," she added. The "Pitch Perfect" star said she never tried to compete with the glamour of Hollywood and would rather use her brain to get ahead. "I've always used my brain to try to get to places... There are so many glamorous people in Hollywood I just never want to compete with that... Even the men get their skin lasered," Wilson said.
