Glee: Divine Duets!

After last week’s three-hanky episode of Glee, the gang lightens up with some duet action. In this week’s episode of Glee, Mr. Schuester (Matthew Morrison) pairs up Mercedes (Amber Riley) and Santana (Naya Rivera), who both look a bit skeptical. Rumors are the unlikely duo will perform River Deep, Mountain High by Ike and Tina Turner. Another reported duet? Rachel (Lea Michele) and Kurt (Chris Colfer) will perform a mash-up of Happy Days Are Here Again and Get Happy. Check out Glee tonight on Fox at 8 p.m.

On the Halloween episode of Glee, New Directions will take on that campy cult hit – The Rocky Horror Picture Show.
