Good news all you Glee fans, John Stamos is joining the cast!

"It's true," executive producer Brad Falchuk to E! news.

"Not sure how many episodes yet," he says, but he's definitely going to become a Gleek!

In tonight's episode of the show, we'll learn that Jayma's character, Emma, is "dating" her dentist. Guess who her hot dentist bf is? Yup, it's John!

John is such a little hottie, we wouldn't mind a little extra eye candy on the show!
