Josh Groban has a PBS special coming out at the end of the month, but fans need not wait any longer to see his incredible performance with Kelly Clarkson.

Groban and Clarkson recorded this duet, "All I Ask of You" from The Phantom of the Opera, for Groban's Stages album, released in April.

“When I was making this record and we were going to record this song, I knew this duet had to be recorded in a very, very special way, and it had to be recorded with a very special singer,” Groban explains in the video above. “[Clarkson] is one of the most versatile singers that I’ve ever heard.”

In the clip, Clarkson stuns in a black off-the-shoulder gown as the pair sings their duet. Fittingly, above the stage, there are numerous chandeliers, and a gentle fog rolls across the stage as they sing. Press play on the video above to see their beautiful performance.

Clarkson spent her summer on the road on her Piece By Piece Tour, but she was forced to cancel her final dates due to doctor's orders. The 33-year-old former American Idol winner shocked the audience at a mid-August concert at Los Angeles’ Staples Center, revealing that she was pregnant after getting emotional while singing “Piece By Piece.” Baby No. 2 for Clarkson and husband Brandon Blackstock will be a boy.

The PBS special featuring Groban and Clarkson's performance is set to premiere on Nov. 28. For more information, check your local station listings online.
