Josh Groban Cast as Ed Helms' Brother on The Office

Singer joins Stephen Collins as another member of Andy's family

"Who is Josh Groban? Kill yourself!"

We love any excuse to use one of our favorite Glee quotes. And even better, the reason behind it involves one of the most awesome casting choices we've heard this season.

We have confirmed the Deadline.com report that funny crooner Josh Groban will be guest starring as Andy's (Ed Helms) brother on this season of The Office…

No word yet on how many episodes Groban will be in, but we hope it's long enough to have some sort of sing-off between the brothers. Based on the singer's hilarious turn on Glee and in Crazy, Stupid, Love, we hope he'll be around a lot this season.

Also cast as a member of the Bernard clan is 7th Heaven's Stephen Collins, who tweeted the news earlier this week: "Doing "The Office" this week. Ridiculously fun & talented group, including @Rainnwilson who I worked w/in his 1st job in '89 in the Park."

Our good friend Jarett Wieselman from ETOnline.com raised a good point on Twitter after the Groban casting news broke. He tweeted: "Josh Groban joins The Office as Andy's brother, while Stephen Collins cast as his dad. Does getting a family = Andy getting Michael's job?" Hm, Helms does seem to be involved with all the latest casting scoop. Maybe Andy is the new Regional Manager of Sabre: Scranton Branch!
