Mischa Barton is letting herself go. Her friends have begged her to take care of her body after recent booze binges have left her bloated and unhappy.

Photos of Mischa with a much fuller face than she’s had recently, have prompted speculation the star’s turbulent love life was causing her to overindulge in food and alcohol.

A source told Britain’s Closer magazine, “When her love life is out of sorts she just lets herself go and hits the party scene. Her friends try to tell her to stop but she doesn’t listen. Drinking bloats her terribly. After clubbing she’ll usually tuck into greasy fast food. She’ll starve herself all day then binge on junk. It wreaks havoc with her system.”

Mischa, Mischa, Mischa. You have a high profile role on a buzzed about TV show. Get your shit together.
