Lindsay Lohan has been sentenced to 90 days in prison for violating the terms of her probation.

The actress appeared in a Los Angeles court on Tuesday to answer charges that she broke the conditions of her bail by failing to attend mandatory alcohol education classes.

Judge Marsha Revel said that she noticed multiple violations stemming from 2007, when Lohan accepted a plea bargain in her DUI case, and would not accept excuses for Lohan's lack of compliance, reports TMZ.

She ruled that the 23-year-old must surrender herself on July 20 to begin the three-month jail sentence.

Lohan broke down in tears at the verdict, telling the jury that she "did the best [she] could".
