Get ready for the Diva-off to end all Diva-offs! Glee’s most powerful — and it’s most spotlight-loving — voices are out in full force for Season 4, Episode 13, which is aptly titled “Diva.”

Santana (Naya Rivera) is back, and appearing in three musical numbers.  Sam (Chord Overstreet), consider yourself warned!  Here’s FOX’s official synopsis of what to expect.

Finn (Cory Monteith) challenges the glee club to find their inner powerhouses for “Diva Week.” Meanwhile, in New York, Kurt (Chris Colfer) can no longer take Rachel’s (Lea Michele) arrogant attitude and calls her out, causing tension between the two friends. Also, Emma (Jayma Mays) is in a whirlwind preparing for her upcoming wedding.

Original airdate: Thursday, February 7 at 9pm on FOX
