Lindsay Lohan has sparked rumors of a drug relapse after witnesses at a number of recent Hollywood soirees say the redundant rehabber appeared stoned.

“She’s hanging out with all her old party friends again. She’s being careful, though, and isn’t being spotted at the clubs. Instead, she’s going to private parties with people she thinks she can trust.”

“Lindsay was acting exactly like she would before she went to rehab,” a spywitness at November 9th late-night party tells Life & Style.

“She and Samantha kept going to the bathroom throughout the night.”

A guest at Paper Magazine’s November 10th party in Los Angeles tells the tab:

“I was trying to talk to her, but it was impossible. She couldn’t comprehend anything.”

LiLo has also ditched her weekly AA meetings, a source told L&S:

“I saw her outside an AA meeting in Westwood on November 13th. She never went into the meeting. She just sat outside talking on her cell phone the whole time. The rehab, the AA meetings-it’s all for show.”

“Her face was puffy and red, and her eyes were despondent. She was acting strange. I’m worried,” a friend added.
