HONOLULU -- Actress Cynthia Watros pleaded guilty on Thursday to drunken driving charges she faced from a traffic stop on Oahu.

The arrest happened early in the morning on Dec. 1.

Watros plays "Libby" in the ABC hit TV series "Lost," which is filmed on Oahu.

Another "Lost" star, Michelle Rodriguez, was also arrested at the same time for DUI. They were in separate cars, one following the other, when they were stopped, according to sources.

Rodrigues, who plays "Ana Lucia" on the show, is scheduled to go to trial on March 30 for the DUI case. Her attorney pleaded not guilty for Rodriguez in an earlier court date.

Watros expressed her apologies to the judge for her actions. Because Watros had no prior criminal record, the judge sentenced Watros to 14 hours of substance abuse counseling and ordered her to pay more than $500 in fines and fees.

"I just want to say that I am extremely grateful for the people of Hawaii for their continued love and support. Thank you," Watros said to reporters after the court appearance.
