Lindsay Lohan was released from a Lynwood, Calif. jail early Monday morning and immediately checked into a treatment center, according to People. Lohan served 13 days of a 90-day sentence for violating terms of her probation in a DUI case. Her early release was due to good behavior and overcrowding.

Lohan has been ordered by the court to spend three months at the treatment facility. She is required to remain clean and sober until August 2011, when her probation term ends, and is subject to a year of random drug testing. Violation of the terms of her probation could have her sent back to jail.
