Tegan And Sara Get the 'Glee' Treatment

Today we have a double whammy:

Not only was a Glee-version of Tegan and Sara's "Closer," the hit song and first single off of Tegan and Sara's seventh studio album, Heartthrob performed in full on last night's episode, they also interviewed Glee star Cory Monteith about his heartthrobs. His first? Sharon Stone from Total Recall! (Read our interview and watch videos here.)

The band also just launched its Closer Karaoke site where fans can sing along to the song, be recorded and have the chance to be featured on a final fan-generated video. Need more Tegan and Sara? The sister act will be performing on The Tonight Show with Jay Leno April 11 and at Coachella April 12 & 19.
