The hip-hop star hired an orchestra to play the singer's track Young and Beautiful when he proposed to the reality Tv star in October (13), and now he is said to have persuaded Del Rey to perform the track in person at their nuptials.
Del Rey has agreed a six-figure sum for the gig, according to Britain's Daily Mirror newspaper.
A source tells the publication, "Kanye knew how much Kim loved Lana's music, which is why he tried to get her to perform at the proposal. So he upped the offer to perform at the wedding and told Lana that it's his and Kim's special song and it would mean so much to have her perform it. She couldn't say no."
The wedding is rumoured to be taking place at the historic Fort Belvedere venue in Florence, Italy on Saturday (24May14).
