Lindsay Lohan: From Rehab to Jail

After leaving rehab 11 days ago, Lindsay Lohan found herself once again in

hot water when she was arrested in Santa Monica, Calif., early Tuesday morning. The actress was

booked on suspicion of drunken driving – and was found with cocaine in

her possession – after a night on the town, according to police.

The previous day, Lohan makes an afternoon shopping date with pals in

Beverly Hills. Later that evening, the actress was pulled over and given a Breathalyzer test after police responded to a call that her SUV was chasing another car. After Lohan failed a field sobriety test, she was arrested.

Lohan later posted $25,000 bail and was released from jail at about 6:30

a.m.

Sporting an alcohol-monitoring bracelet, which she was wearing voluntarily,

Lindsay spent an afternoon at Malibu's Polaroid Beach House on Sunday.

At the time, Lohan was planning on getting back to work filming Dare to Love Me – for which the actress reportedly had been taking

Tango lessons. Now those plans may be on hold.

Following her day soaking in the sun at the beach house, Lohan goes undercover when she joins some friends for dinner at Taverna Tony, a Greek restaurant in Malibu, on Sunday evening.

Continuing with her active nightlife, Lohan makes a post-clubbing stop at

Mel's Diner in West Hollywood last Tuesday night, following an evening out with friends that began at hot spot Les Deux.

After a busy social weekend – which included a trip to Las Vegas, a brief stop at the Rock amp Republic 5th Anniversary Party in Santa Monica, and a visit to Los Angeles club LAX on Sunday – Lindsay takes it easy with a low-key outing in Beverly Hills on Monday.

The day after completing a 45-day stint in rehab, Lindsay Lohan and some pals jetted out for a night on the town at Pure Nightclub in Las Vegas on Saturday. At the time, rep Leslie Sloane said of her client: "She's doing great. Lindsay is working hard on her sobriety and we are all supporting her."
