Less than 24 hours since she was released from rehab, Lindsay Lohan emerged Wednesday in a Beverly Hills parking garage with a drink – an energy drink – in her hand.

The actress, 24, clad in an all black ensemble, sunglasses and headphones around her neck, was spotted for the first time since serving 13 full days in jail and spending three weeks at UCLA's Resnick Neuropsychiatric Hospital.

Following her release from rehab, Lohan, who is now in UCLA's outpatient program, was ordered to psychotherapy treatment and will also be required to submit to random drug and alcohol testing twice a week.
