'Glee' returns next month with its spring premiere episode in which fans are introduced to Blaine Anderson's older brother, Cooper.

In the 'Big Brother' episode, Darren Criss shares the screen with 'White Collar' star Matt Bomer, whom he refers to as "ever handsome and dashing" in a sneak peek of the show. "I finally get to meet other people in the Anderson family, as does the whole 'Glee' world," Criss says.

"It was great to suddenly find myself in their sandbox and in the choir room," Bomer adds. "I feel like being a fan of the show helped me to jump into the world a little bit easier than if I'd never seen it before."

Criss and Bomer offer a dramatic rendition of Gotye's 'Somebody That I Used to Know' in the show. "I love everything about it," Bomer gushes about the hit tune. The talented actors also get to perform a Duran Duran mashup.

But that's not all, Gleeks. Other highlights of the upcoming show include a kiss between Sue and Cooper (for reals), and the outcome of Quinn's car accident. The 'Big Brother' episode will air on Tuesday, April 10 at 8PM on FOX.
