Cowell's rolled eyes 'killed' Buble
Michael Buble has told how his confidence was shattered by Simon Cowell - after the X Factor judge gave him a withering look.
The Home singer said he fell apart after Simon rolled his eyes during a performance on American Idol in 2007 - to the extent that people thought he was drunk.
Michael told the Radio Times: "I had to sing Call Me Irresponsible in front of 20 million people. And the first thing I saw when I got on stage was Simon Cowell.
"I sang about four lines and he looked at me and did this (rolls his eyes dismissively) and that was it, I was done. It killed me. My confidence dropped."
Michael said he becomes more "aloof" when he has a crisis of confidence.
"I get the attitude of, 'Oh really? Well, f*** you.' And if you watch the clip on YouTube, I'm so aloof I look bored.
"And it became quite a thing for me in America because all the news agencies started to report that I was drunk. But I'm such a control freak I would never drink before going on stage."
Simon only heard about the episode when Michael told Dannii Minogue some years later.
"She goes and tells him, and comes back saying this: the man didn't even know he did it. He was just probably sitting on his fifth hour of the show going, 'Kill me now ... and I've got to go to the bathroom.'
"But I'm so sensitive I took it as a rejection. Anyway, every time I've ever talked to him since then he's been incredibly nice," he added.
