Mr. Schuester is about to get some serious competition -- and it could be in the form of the sexy John Stamos.
According to EW, Stamos is in talks to join "Glee" next season as another love interest for Emma, the OCD guidance counselor played by Jayma Mays.
Chances are Stamos will sing on the show -- he starred in "Bye Bye Birdie" on Brodway ... and logged some serious time playing with Jesse and the Rippers on "Full House."
