'Glee' Sneak Peek: Darren Criss and Matt Bomer Sing Gotye's 'Somebody That I Used to Know'

'Glee' Sneak Peek: Darren Criss and Matt Bomer Sing Gotye's 'Somebody That I Used to Know'

"Glee"'s return on April 10 will be marked by brotherly love -- or at least brotherly harmonizing.

The upcoming episode, titled "Big Brother," will introduce viewers to Blaine Anderson's big brother, TV pitchman Cooper Anderson (played by Matt Bomer of "White Collar.")

Unfortunately, the sibling reunion doesn't go as smoothly as hoped, but as always with "Glee" that's nothing that the healing power of song can't cure -- hence the brothers' duet of Gotye's "Somebody That I Used to Know."
