Buble admits 'I was a dork'

Canadian singer Michael Buble admits he was once a dorky school kid but says he's now lapping up the attention of his newfound fame.

Asked if he was popular at school, Buble said: "Not at all. That's why I'm doing this. I got beat up a lot and kind of tried to use humour to protect myself.

"I am outgoing to protect myself because I am really self-conscious in a weird way."
