. It's also been alleged that the star has smelled of booze on several occasions.

The troubled actress was supposed to have completed her stay at the Cirque Lodge rehab clinic in Sundance, Utah, last week after nearly two months of intensive therapy.

Insiders say cocaine isn't the only drug she's taken during her time at the facility, with the actress said to have mixed diet pills with anti-anxiety medication in a bid to get a high.

"I think she'll take whatever pills they allow her," says an insider. "It's obvious to me she's high because she acts loopy and can't seem to walk in a straight line!"

The source says Lindsay's so-called friends and some staff at Cirque Lodge are equally to blame, with pals smuggling alcohol into the clinic and star-struck staffers turning a blind eye to her rule-breaking.

"She had a friend sneak vodka in a water bottle into one of the Alcoholics Anonymous meetings she goes to," reveals the insider. "Everyone wants her to be their friend, so they'll do anything for her."

Another source confirms that some staff at the center are doing little to curb Lindsay's bad behavior. "She smells like booze, and [they] do nothing about it," says the source.
