La Bamba Star Arrested

TMZ has learned that actor Lou Diamond Phillips was arrested early Friday morning for alleged domestic violence.

Police were called to a home in Northridge, Calif. around 2:00 a.m. and found Phillips and his live-in girlfriend in an argument. The couple had apparently gotten into a heated verbal argument that escalated and became physical. Phillips was arrested and taken to the Devonshire police station where he is currently being held on $50,000 bail.

Phillips is perhaps best known for his portrayal of 50's teen idol Ritchie Valens in "La Bamba" and has most recently been seen on NBC's "Law & Order: SVU" and various other TV guest star appearances.
