Lindsay Lohan's lawyer quits

LOS ANGELES, July 9 (UPI) -- A representative for Shawn Chapman Holley says the attorney is no longer working with troubled U.S. actress Lindsay Lohan.

People.com said no details were released regarding why they parted ways.

Beverly Hills, Calif., Judge Marsha Revel sentenced Lohan Tuesday to 90 days in jail and 90 days of in-patient rehabilitation for violating probation.

Revel said Lohan failed to attend court-ordered alcohol education classes, thereby violating her probation in a 2007 conviction for driving under the influence.

A close-up photo taken in court of Lohan's middle finger, which clearly shows the words "F--- U" scrawled on the nail, was widely published after the hearing, prompting media criticism of the starlet's behavior. Holley defended Lohan at the hearing and was by her side when the photo was snapped.

"We got a call yesterday from a female identifying herself as Tiffany Feder-Cohen," L.A. Sheriff's spokesman Steve Whitmore told People.com Thursday.

"She introduced herself as Lindsay Lohan's new attorney. I can't get into details about why she called, but the bottom line is that we at the sheriff's department only do what the courts instruct us to do."

The Web site said its calls to Feder-Cohen's office were not returned.

Lohan, 24, is best known for her roles in the movies "Mean Girls," "Freaky Friday" and "The Parent Trap."

She is scheduled to surrender July 20 to begin serving her sentence at the Century Regional Detention Facility in Lynwood, Calif.
