Troubled actress Lindsay Lohan will be randomly tested for drugs and alcohol until August 2011 after she serves 90 days behind bars.
She was sentenced for violating the terms of her probation stemming from a 2007 DUI (Driving Under Influence) arrest on Tuesday. She will also be spending another three months in rehab.
Lohan broke into tears in the courtroom on Tuesday as Judge Marsha Revel announced her judgement, reports contactmusic.com.
The 24-year-old avoided arrest in June when her representatives posted part of a $200,000 bail after an alcohol bracelet detected that she had been drinking after the MTV Movie Awards in Los Angeles.
The court asked Lohan to wear the bracelet earlier this year as part of her probation after two previous convictions of drunk driving dating back to 2007.
