Lindsay Lohan was seen partying in Los Angeles at the weekend - just weeks after leaving rehab.

The 'Mean Girls' star looked dishevelled and worryingly thin in the toilets of the plush Hollywood Roosevelt hotel where she had been partying at exclusive nightclub Teddy's on Saturday night (03.03.07).

After spending 10 minutes in a cubicle, Lindsay - who was wearing a pair of oversized sunglasses - breezed out of the toilets followed by a group of girls.

One fellow reveller, who had been partying at the hotel's Tropicana Poolside Bar, said: "She looked really thin and tired, although it was quite difficult to tell if she had been drinking. Most of the other girls were surprised when they found out they had been sharing a rest room with a Hollywood A-lister.

"She tried not to look at anyone as she left, but one girl noticed her and said, 'That was Lindsay Lohan! Hasn't she just come out of rehab?' "

After her trip to the toilets, Lindsay, 20, was seen heading back to the nightclub.

It is not the first time the 'Bobby' star has enjoyed an evening at Teddy's since leaving Los Angeles' Wonderland rehab centre on February 16.

Lindsay performed a DJ set there last month before leaving with 'Jackass' star Steve-O.

Lindsay recently admitted she was "really sick" before checking into Wonderland for alcoholism.

She said: "I was really sick. I went to the hospital and had people sit me down who said, 'You are going to die if you don't take care of yourself.'

"I heeded what they were telling me."
