A well-known pop singer has been tapped to play Andy Bernard’s brother on NBC’s "The Office," according to The Hollywood Reporter’s Live Feed blog.

Singer Josh Groban will play the role of Walter Jr. in the show’s eighth season, the story reports. Groban’s role at this point is just for one episode, which will air sometime this fall.

Groban recently appeared in the Steve Carell romantic comedy "Crazy Stupid Love" and was seen performing Kanye West’s tweets in song form, the piece notes.

The casting move comes on the heels of the news that veteran TV actor Stephen Collins was cast as Andy Bernard’s dad for an October episode, as previously reported. Ed Helms plays Andy.

Dee Wallace will reportedly appear as Andy’s mom.
