Michael Buble Wants Robbie Williams Duet

Michael Buble wants to team-up with Robbie Williams to record a duet.

Buble confesses to being a big fan of the ex-Take That singer and would "love to do a duet some time."

Michael even stuck up for Robbie following the mixed-reception of his recent X Factor performance - which caused some fans to speculate he was out of it.

Buble adds to The Sun: "People are very quick to jump on a guy and say 'he's high' or 'he's drunk' but Robbie was getting up on stage for the first time in three years. Give the guy a break."

"I can seem a bit loose and apparently some people thought I was drunk. So I felt for Robbie."

This week Buble denied he is clean-cut.
