You two may be coming on board Glee later this season, but the April 10 return episode of this Fox musical is all about a different guest star: Matt Bomer.

The White Collar star will appear on "Big Brother" as Cooper Anderson (think about it... then laugh!), Blaine's sibling who is best known for his Free Credit Rating Today commercials. In the following behind-the-scenes video, we watch interviews with Bomer and Darren Criss, along with footage from the installment, which includes a Cooper cover of "Somebody That I Used To Know."

Check it out now and then view the latest Glee trailer for the spring premiere:
