HEMPSTEAD, N.Y. -- Actress Lindsay Lohan's mother has pleaded guilty in New York to a misdemeanour charge of driving while intoxicated.

Newsday reports Dina Lohan also pleaded guilty to speeding during her court appearance Tuesday on Long Island.

The Nassau County prosecutor says Lohan is expected to be sentenced June 3 to a conditional discharge and 100 hours of community service. She will also pay a fine.

Police said Lohan was driving 77 mph in a 55 mph zone when she was arrested on Sept. 12 in Oyster Bay. They said her blood alcohol level was more than double the legal limit.
