Washington, July 22 : Former The O. C. star Mischa Barton has been struggling with a fluctuating weight and body image, it has been revealed.

"She has big self-esteem issues. ... She hates her legs," People magazine quoted a source close to Barton as saying.

"She isn''t comfortable with her body. It''s been a big source of stress and self-hate," she added.

According to a friend, the photos of her cellulite released by media really upset her.

"[She was] more pissed off than hurt and she complained a lot about that" – she didn''t let them get "to her too much. ... I never saw her diet," said a friend.

Another source added, "She had a big problem with those photos of her cellulite. … She didn''t like it. That just was something that contributed to her spiraling but she didn''t do much to fix it because of her partying."
