Poor, poor Kourt.
The source says of Disick:
Be still our hearts!
Justin Bieber was performing in London again this evening when he experienced super SERIOUS breathing troubles on stage!
Eye-witnesses say he even passed out during his performance!
He was rushed backstage and manager Scooter Braun reportedly said the 19-year-old superstar was "very low on breath."
Only then did he allow his peeps to rush him off to the hospital to see what was wrong.
He rep confirmed the bad news, saying:
"He got oxygen from emergency personnel. He insisted on finishing the show. He is on the way to the hospital right now."
We love you, Justin! We hope this is nothing too serious!!
More details surely come…
