AceShowbiz - 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" hitmaker 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 keen 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?"

Katy Perry previously confessed she has a lesbian crush on Cheryl Cole, saying "I adore Cheryl - she's amazing. I'm very happy with my own English stud but if I wasn't with him I'd be trying to date Cheryl." She even compared Cole to Simon Cowell, "I know people get turned on by Simon's power but if I was single I'd rather sleep with Cheryl than Simon."
