LOS ANGELES, California?US actress Lindsay Lohan was released from a county jail early Monday after serving 13 days for violating probation on a 2007 conviction for driving under the influence, The Los Angeles Times reported.

The newspaper quoted sheriff's spokesman Steve Whitmore as saying that after her release at 1:35 am local time (0835 GMT), Lohan was to go directly to a substance abuse treatment center.

The treatment facility was not identified, but Whitmore said Lohan had left the prison in a minivan with multiple individuals, the report said.

Lohan has been locked up the Century Regional Detention Facility in Los Angeles since July 20 but she was kept away from other inmates for security reasons.

Lohan, who starred in the 1998 film "The Parent Trap" and 2003's "Freaky Friday," was arrested in May 2007 after crashing her Mercedes in Beverly Hills.

After a stay in rehab, the star of "Mean Girls" and other hit films was caught two months later for drunk driving and cocaine possession. At the time, she spent a mere 84 minutes in jail.

The actress has completed an alcohol education program, but was found in violation of probation because she did not attend classes regularly, The Times noted.

Despite a tough period adjusting to jail life, Lohan remained cooperative and became more subdued as days passed, according to law enforcement sources, the paper said.
