BEIJING, July 20 (Xinhuanet) --"Mean Girls" actress Lindsay Lohan was a "fidgety mess" just hours before starting her 90-day jail sentence for violating her probation, according to AFP reports.

"She is a nervous, fidgety mess, and her legal team, family and friends are very concerned about her fragile state," a source told People magazine.

The troubled actress has been spending her last free days at the so-called "Sober Living House" in LA and tweeting about how much she doesn't like her father.

Actress Lindsay Lohan addresses the court before her sentencing for violating her probation on a 2007 drunken driving charge in Beverly Hills, California July 6, 2010.

She said, "I don't like my ex-father anywhere near me no matter where I am. He is crazy and scares me."

Lohan was arrested on suspicion of drunken driving in May 2007 when she drove a Mercedes-Benz that crashed into a hedge on Sunset Boulevard near the Beverly Hills Hotel.
