WATCH: Kelly Clarkson and Josh Groban Sing ‘All I Ask of You’ from ‘Phantom of the Opera’
Groban surprised the audience when he announced that a special guest would be joining him for a surprise performance together.
The duo earlier collaborated on a duet of the song for Josh’s Stages Broadway musicals cover album, so Clarkson is no stranger to performing Groban.
Clarkson admitted that the Phantom of the Opera was the first musical she’d ever seen as a child and therefore held a special place in her heart.
Reactions from the audience couldn’t have been happier as they were spotted mouthing the words along with the twosome, big smiles on their faces.
