LOS ANGELES -- Lindsay Lohan's new lawyer, Robert Shapiro, says he agreed to represent the troubled actress only if she does her jail time and complies with the terms of her probation.
He also said he would help Lohan get treatment to accomplish long-term recovery and sobriety.
"Ms. Lohan is suffering from a disease that I am all too familiar with," said Shapiro, whose son Brent died of a drug overdose in 2005.
"Hopefully I can be of assistance."
Lohan is scheduled to begin serving a 90-day jail sentence on Tuesday.
Shapiro, a member of O.J. Simpson's 'Dream Team' has represented numerous celebrity clients and has been working for substance abuse treatment since the death of his son.
He established the Pickford Lofts sober living facility, a treatment center where Lohan is temporarily staying.
Revel sentenced Lohan to 90 days in jail for violating her probation in her DUI case, followed by a 90-day inpatient rehab program.
