Michael Buble on Simon Cowell
Michael is still upset with the music mogul for "killing" his confidence during a performance.
The Canadian crooner was performing 'Call Me Irresponsible' during 2007's American Idol when Simon apparently snubbed him.
He told the Radio Times: "The first thing I saw when I got on stage was Simon. I sang about four lines and he looked at me and [rolled his eyes] and that was it, I was done. It killed me. My confidence dropped."
"Maybe Cheryl Cole gets a little quiet and more demure when she loses her confidence. But I become aloof."
Michael went on to reveal that he may have taken it the wrong way after talking to former X-Factor judge Dannii Minogue.
"I told her the story. She goes and tells [Cowell], and comes back saying, '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."
Meanwhile, Michael's celebrating a victory in one of the closest chart battles in recent US history.
His Christmas album edged out Nickleback's Here and Now by 0.18% in the album chart with Rihanna's Talk That Talk just behind them at number three.
