Lindsay Lohan has reportedly cut ties with her sobriety circle to continue partying in Europe.

The Mean Girls star, who completed her sixth stint in rehab last summer, moved to London recently in a bid to get her career on track.

Since then, the 28 year-old actor has been spotted partying, tripping over and looking in worst shape than ever, events which have sparked concern in her friend circle.

According to a report on RadarOnline.com: "Everyone thinks Lindsay moved to London because she knows she can get away with things there that she cannot get away with here. She's cut ties with everyone back in the States."

The actress's support networks in New York City and Los Angeles are fed up with her reckless behavior, the source revealed. "You can only give someone so many chances. She's not answering phone calls from her sober friends. It's frustrating."

Lindsay, who is set to make her theatre debut in the upcoming West End production Speed-The-Plow in London later this year, recently insisted her wild partying days are behind her.

She said: "I'm at a place in my life where I like the commitment. I'm looking forward to that part of it."

She also said London have had "a calming influence" on her life.
