Source: Robert Shapiro Stepped Down as Lindsay Lohan’s Attorney

A source close to attorney Robert Shapiro tells ET that he left Lindsay Lohan's case on his own accord.

According to the source, Lohan "did not meet the guidelines [Shapiro] set up to represent her."

Last Wednesday, Lohan admitted herself to a sober living facility owned by Shapiro. During her stay, she received visits from friends and family, such as mom Dina, sister Ali, and ex-girlfriend Samantha Ronson.
