The Daily Star Sunday reports that Kate Middleton and groom Prince William are big fans of the musical pair, and that thanks to the fact they are currently in Europe promoting Beyonce's new track Run The World (Girls), the gig is a done deal.
A source said: "Both William and Kate are massive fans of Beyoncé 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?
"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 ditch traditions and make it more personal for them."
Check out the trailer to Beyonce's new single below.
