Poor, poor Kourt.
The source says of Disick:
OMG! It's the duet we never knew we absolutely HAD TO SEE!
Sara Bareilles will be performing a duet with the legendary Carole King!
Speaking of that megabit, what song do you think they'll perform?
The unfortunate thing about a list of hits as long as Carole's is that it's so hard to choose! Where You Lead, A Natural Woman, Will You Love Me Tomorrow?
Who can choose?? Here's hoping for a medley!
But no matter what they sing, we just know it's going to be Some Kind Of Wonderful!
