A rep for the actress had no comment on the report.
The paper’s story also includes what it says are screen grabs from video clips of Lohan, 20, inside the ladies room of Teddy’s nightclub in the Hollywood Roosevelt Hotel, with two friends who are also allegedly taking drugs. (PEOPLE has not seen the video.)
Lohan also is quoted boasting about her sexual conquests among celebrities, while unnamed “friends” of the actress, according to the paper, said her drug-taking began at 8 p.m. one night and was still going on at 11 a.m. the next morning.
While Lohan has talked about attending Alcoholics Anonymous meetings, the same unnamed sources claimed that her water bottles are filled with vodka, according to the paper.
In January, the actress checked into the Wonderland Center, an addiction-treatment facility in the residential neighborhood of Laurel Canyon in Los Angeles. Reflecting upon her stay there, Lohan told Allure that she had awakened at home on Jan. 17 to a house surrounded both on the ground and in the air by paparazzi.
She then checked out Wonderland and found “a quiet room, all white, with parquet, and it was different! I just felt safe,” she said. “I thought, ‘I’m going to stay here tonight.’ And I stayed there. For a month. It was great.”
