N-Dubz and Jessie J have offered possible first dance suggests for Prince William and Kate Middleton.

The couple are set to tie the knot on Friday (April 29) and there is huge interest around what music they'll choose for the ceremony.

Speaking to BBC Newsbeat, N-Dubz said it would "be nice" for the first dance to be 'Firework' by Katy Perry.

Jessie J offered some more unexpected suggestions.

"R Kelly 'Bump 'N Grind' just because I think it would be incredible to watch," she said. "Or 'Whip My Hair' [by] Willow Smith. I'd love to see Kate whipping her hair."

The Royal Wedding takes place at Westminster Abbey in London.
