Singer Katy Perry wants to give Simon Cowell an extra special wedding present - by performing a duet with his TV colleague Cheryl Cole at the ceremony.

The I Kissed A Girl hit-maker befriended Cowell and Cole when she stood in for Australian singer Dannii Minogue on the judging panel of Britain's The X Factor earlier this year.

And now Perry is eager to collaborate with the Girls Aloud star when Cowell finally walks down the aisle with Mezhgan Hussainy.

She tells Britain's Now magazine, "I'd love to perform with Cheryl and I think a great time to do it would be at Simon's wedding - what else do you get the man who has everything?"
