'The Canyons' star finished her 90-day court ordered rehab stint on July 30, and just days later stayed up with the British boy band in Los Angeles.
A source told the New York Post newspaper: "The party went on all night long and was so loud that guests were complaining. Lindsay was there with [the band's] Max George. The Wanted have been staying at the Mondrian [hotel] for days, and Lindsay, who briefly dated Max a while back, was partying with the band.
"There were so many complaints about the noise that hotel staff had to shut the party down and Lindsay had to be taken out of there by security at 7am. She was with her sister."
A representative for the actress confirmed she visited Max, but it is thought she remained sober, as she has been since leaving rehab.
Lindsay has now moved to New York City, and has been following advice given to her by talk show host Oprah Winfrey, who believes she's finally beaten her demons.
Oprah said: "I thought that she's in the best place that I've ever seen her. I believe that she believes that she is now ready. And she admitted that there were other times when she was pretending to be ready and not quite sure. And sometimes resentful that she was being, you know, put in a position where she had to go to rehab. I think this is the first time I could see it really benefited her."
