London: R&B star Beyonce is all set to perform at the wedding reception of Prince William and Kate Middleton along with rapper husband Jay-Z.

The 29-year-old pop diva was invited by the prince and his bride-to-be Middleton, to perform the R&B love song-Crazy in love-which also features Jay-Z, at the royal ceremony.

"Both William and Kate are massive fans of Beyonce and Jay-Z. They really wanted to make their big day even more special and what better way than by getting pop royalty to perform at the party?" said a source close to the Royals.

The singer is rumoured to have accepted the invitation to appear at the much-awaited wedding of the year.

"Jay-Z and Beyonce are both in Europe at the moment while she promotes her new single 'Girls Who Run The World'. So it's highly likely they have taken up the Royals' offer. After all, who would turn down a once-in-a-lifetime gig like that?" added the source.

However, the palace officials are yet to confirm the acceptance of the invitation.
