Michelle Rodriguez was sentenced to six months in county jail on Wednesday for violating her probation in a DUI case.

"[She] admitted violating her probation by failing to provide proof of completion of her community service and for consuming alcohol three times while wearing an alcohol-monitoring device," said the L.A. City Attorney's office in a statement. "She did file a document that said she completed community service on September 25, but we obtained evidence that she was in New York that day."

The Lost alum was originally sentenced to complete 30 days of community service as part of her probation for a DUI case, in which she pleaded no contest to a hit-and-run, driving with a suspended license, and driving under the influence of alcohol in two incidents in 2003. Rodriguez then violated her three year probation when she was arrested in Hawaii on a DUI charge in 2005.

Rodriguez was ordered to spend 60 days in jail, but served less than a day because of jail overcrowding in May 2006. She was then ordered to perform community service and remain on probation until June 2009.
