'American Pie' star Chris Klein arrested on DUI, may face jail [update]

chris-klein-busted.jpg C hris Klein -- best known for starring in "American Pie" and being Katie Holmes' longtime beau before Tom Cruise, and, oh yeah, dating Ginnifer Goodwin  -- was arrested early this morning on suspicion of DUI.

The clean-cut actor was pulled over on the LA 101 freeway at 3:13AM. Klein, 31, failed a sobriety test. Sources say his blood alcohol level was three times the legal limit.

The sad news is this is not his first DUI. He was arrested and convicted of DUI in 2004. And California law states that he serve a minimum 4 days in jail if he's convicted of DUI again.

TMZ reports that Klein wasn't alone when he was pulled over.
