London: The royal wedding reception of Prince William and Kate Middleton is all set to witness a rocking performance by Pop Diva and her rapper husband Jay-Z. The duo will perform ‘Crazy in Love’ before a number of celebrated invitees.

The 'Single Ladies' hitmaker was invited by the royal couple itself, to perform the R&B love songs.

"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.

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

According to the source, "Will and Kate will have an official reception for hundreds of dignitaries before throwing a less formal bash for loved-ones. They both wanted to dike traditions and make it more personal for them”

"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 that 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.
