As previously reported, Bomer and Criss will perform a mashup of "Hungry Like a Wolf" and "Rio" from '80s rock band Duran Duran. The duo also performs "Somebody That I Used to Know" by Belgian-Australian singer and songwriter Gotye, and Blaine covers Christina Aguilera's "Fighter."

Here's how Fox describes "Big Brother": "Much to Blaine's chagrin, his big-shot Hollywood actor brother, Cooper (Bomer), comes to visit."

Fox has announced that the series will be renewed for a fourth season. Fox's "New Girl" and "Raising Hope" have also been renewed. "Raising Hope" stars Tony nominee Martha Plimpton (Pal Joey), Garret Dillahunt (Inherit the Wind), Cloris Leachman (Masquerade) and Lucas Neff.

Bomer, best known for his work on USA Network's "White Collar," has also been seen in "All My Children," "Guiding Light," "North Shore" and "The Texas Chainsaw Massacre: The Beginning," among others. The actor also recently signed on to play Felix Turner in the film adaptation of Larry Kramer's The Normal Heart.

"Glee" airs Tuesday nights on Fox at 8 PM ET. To watch the performance of "Somebody That I Used to Know," look below:
