Lindsay Lohan has checked out of the Betty Ford Center in Rancho Mirage, Calif., according to her lawyer, after beginning her court-mandated, three-month rehab stint at the facility last month.

"Lindsay is grateful for the treatment she received at the Betty Ford Center," her lawyer, Shawn Holley, told ABC News in a prepared statement. "She has completed her course of treatment there and looks forward to continuing her treatment and building on the foundation established at Betty Ford."

In March, Lohan, 26, pleaded no contest to lying to police and reckless driving stemming from a 2012 car accident in Santa Monica, Calif. She accepted a plea deal that involved three months of rehab, 30 days of community labor, a fine and 18 months of psychological counseling.

To complete her mandatory rehab sentence, Lohan has reportedly checked into another rehab facility in Malibu, Calif., a source told People magazine, that is "better suited for long-term care."
