Lindsay Lohan's girlfriend Samantha Ronson has been admitted to a hospital in California - reportedly suffering from exhaustion and depression.

The DJ is said to have called doctors to her Los Angeles home on Sunday and was subsequently taken to the Cedars-Sinai Medical Center.

A source tells Life and Style magazine, "She's been suffering from depression and from lack of food and sleep. Lindsay Lohan has been helping her through this as she has been through it herself two years ago."

Celebrity website TMZ.com is reporting that Ronson has been admitted to the hospital, but claims the visit is "not an emergency and definitely non life-threatening."
