Actress Jaime Pressly has been arrested in Santa Monica for investigation of driving under the influence of alcohol.
Lt Darrell Lowe said the co-star of TV's My Name Is Earl was stopped for a traffic violation and booked on suspicion of DUI but would not release further details. Pressly's blood-alcohol level wasn't immediately released.
The Los Angeles County sheriff's website said the 33-year-old actress-model spent the night in jail and was released yesterday morning after posting $15,000 bail.
Pressly is best known for playing Joy on the NBC sitcom.
She was twice nominated for an Emmy for Outstanding Supporting Actress In A Comedy Series, winning the award in 2007.
She has also been nominated for a Screen Actors Guild Award and a Golden Globe Award.
An email to her manager seeking comment wasn't immediately returned.
