Lindsay Lohan is in the middle of even more legal drama.

Thursday afternoon – just hours after Lohan’s attorney Shawn Chapman Holley released a statement calling the star’s 90-day jail sentence “harsh” – Holley suddenly resigned as Lohan’s lawyer.

A rep for Holley confirmed the lawyer is no longer representing Lohan, but would not release any more details.

However, it seems Lohan may have already hired a new attorney in her criminal case, according to police.

“We got a call yesterday from a female identifying herself as Tiffany Feder-Cohen,” says L.A. Sheriff’s spokesman Steve Whitmore. “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.”

Calls to Feder-Cohen’s office were not returned.

“Lindsay is determined to not go to jail, get new attorneys and just appeal it,” says a source close to the actress. “She seems totally with it, smart and knows what she wants.”

But a legal expert says the chances of winning an appeal are slim to none.

“There is absolutely zero chance of Lindsay winning an appeal because there’s overwhelming evidence of her repeatedly violating her probation and the court’s orders,” says criminal defense attorney Trent Copeland, who’s not involved with the case. “That is undisputed.”
