While Glee fans prepare to bid farewell to their favorite show tonight, a major piece of casting news should at least keep them buzzing all summer long:

As first reported by EW.com, John Stamos has signed a deal to recur on season two of this Fox smash!

What role will Stamos likely play? Competition for Will.

As previously reported, Emma will reveal to Will on this week's finale that she has fallen for another man: her dentist. The former Full House star will take on this character and, it's safe to assume, sing-off against the leader of New Directions for Emma's heart next season at some point.

Stamos does have a musical background: he's starred in Bye Bye Birdie on Broadway, along with other productions.

What do you think of this casting choice?
