Sean William Scott leaves rehab!

Sean William Scott has left rehab.

The 34-year-old American Pie actor was voluntarily admitted to a clinic in March for “health and personal issues” but has now left, celebrating by going to see a Knicks basketball game in New York.

“He completed the 30 days successfully he’s doing great,” a source told TMZ.

“Seann dealt with an issue and hopefully he can do American Pie 4 and re-energize his career.”

Despite parts in films including Role Models and The Dukes of Hazzard, Seann has remained best known for playing obnoxious, hard-drinking college student Stifler in the American Pie franchise, and fans have struggled to separate him from this alter ego.

“I walk down the street and someone’s like, ‘Hey we’ll buy you a shot.’ And I’m like, ‘No, I’m OK’,” he said. “They’re so crushed, like ‘What? But you were in American Pie‘ I say, ‘It’s a movie.’”

Although previously distancing himself from the character which he last played in American Pie: The Wedding in 2003 Seann is in talks for a fourth film in the series, American Reunion.
