At a hearing in Beverly Hills Friday, Los Angeles Superior Court Judge Marsha Revel slapped an extra year on Lindsay Lohan’s existing three-year probation sentence after the dishelved star showed up to the courthouse more than an hour and a half late.

Lohan had been ordered to appear for a progress review in her two DUI cases. According to TMZ, Lindsay’s court date is due to her lack of attendance at the Right On Programs, a condition of her probation. Lindsay reportedly took a leave of absence from the alcohol education program to work out of state – but did not return to the classes until recently.
