Lindsay Lohan celebrates 100 days of sobriety

Troubled actress Lindsay Lohan is successfully celebrating 100th day of her sobriety, it has emerged.

The Mean Girls star, 24, has gone 100 days since her last positive drug and alcohol test and is successfully staying away from the substances that have landed her in rehab, reports RadarOnline.com.

Since entering the Betty Ford Center in Rancho Mirage, California, Lohan has been earning privileges to leave on day trips, work, and even drive again. All of which are part of the recovery Los Angeles Superior Court Judge Elden Fox hoped to achieve when he sentenced the actress to the treatment center until January 3, 2011.

Lohan is taking her sobriety seriously, according to her mom Dina, and is looking forward to working again in the New Year.

Her father Michael wished his daughter well and said: "I hope she has a decade more."
