'Glee' To Welcome John Stamos Next Season

'Full House' and 'ER' alum will play a dentist who dates Emma and butts heads with Will.

Uncle Jesse is about to become the newest member of the Gleek nation. John Stamos, the former star of both "Full House" and "ER," is set to take on a recurring role in the next season of Fox's hit musical series "Glee."

"It's true," the show's executive producer, Brad Falchuk, confirmed to E! Online. "Not sure how many episodes yet."

According to Entertainment Weekly, Stamos will play a dentist who begins dating his patient, the germophobic guidance counselor at William McKinley High School, Emma Pillsbury (Jayma Mays). On Tuesday night's (June 8) season finale, Emma well mention that she's started dating the guy she pays to clean her teeth, setting up Stamos' arc next season.

That story line will surely bring him into conflict with Matthew Morrison's Will Schuester, the glee-club director who fans are hoping finally gets together with Emma for real. Word is that Will and Stamos' characters will find themselves butting heads — and vocal cords — during a sing-off next season. Stamos might give Morrison a run for his money, as the "Full House" star has performed with the Beach Boys and appeared on Broadway in productions of "Cabaret" and "Bye Bye Birdie."

As E! Online pointed out, Stamos is actually not a total stranger to "Glee," having popped up in a way last year. This past September, Emma delivered the zinger: "They say it takes certainty more than talent to make a star. I mean, look at John Stamos."
