US actor Seann William Scott, who shot to fame in the popular "American Pie" movies, was beginning a stint in rehab Wednesday for "health and personal issues."

Scott, 34, who also starred in "Dude Where's My Car?" entered treatment voluntarily, his reps told People.com. They did not disclose where he was being treated or what prompted him to seek help.

"Seann William Scott has voluntarily admitted himself for proactive treatment to address health and personal issues," the reps said in a statement. "He appreciates the support of his many fans at this time."

The actor is famed for his role as oversexed, party animal Steve Stifler in the popular "American Pie" franchise, but in a 2003 interview with People.com, Scott said, "I don't do drugs or alcohol. I don't party. I don't watch porn."
