Poor, poor Kourt.
The source says of Disick:
At least we think that's what happened, LOLz!!
How else could you explain the flawless rendition Kelly Clarkson performed at the Molson Ampitheater last night in Toronto?
Her lips opened and the delightfully smooth vocals of Michael Bublé leaked out!
Ch-ch-check out her competent cover of the Grammy-winning artist Home (above)!
You can hear the slight fan disappointment when KC tells her audience the Canadian cover they were receiving wasn't an Avril Lavigne track or perhaps even You Oughta Know!
They'll get over it! This pop perfection could probably poop her pants on stage and it would still come out smelling like roses!
