In addition to the Madonna-themed episode, Cory Monteith tells E! Online about what Finn-related spoilers we can count on before the season finale:
Spoiler alert time! The breakout star also dished that Finn will find out he's not the father of his cheerleader girlfriend's baby before the season's over. Mr. Schuester will also find out his wife is faking her pregnancy.
"It's going to cap off the season," said Monteith. "You will definitely see a lot of juicy stuff."
