Dina Lohan, Lindsay Lohan's mother, pleaded guilty to aggravated Driving While Intoxicated and to speeding while appearing in front of a Long Island judge on Tuesday. Courtroom sources told TMZ, Lohan will have her license revoked and an interlock device installed on her vehicle as part of her sentence. In addition, she'll need to complete 100 hours of community service, attend a drinking and driving program as well as a victim's panel and pay all fines and fees related to her September arrest. Lohan, 51, was pulled over in Long Island on September 13 after officials caught her driving at 77 mph in a 55 mph zone. At the time Lohan's blood alcohol level was more than twice the legal limit.
