Del Rey to perform at Kimye wedding
The 27-year-old singer's hit Young And Beautiful is one of Kim's favourite songs and Kanye organised for a brass band to perform it when he proposed at a baseball stadium in San Francisco last year.
Lana will be flown to Paris to serenade the happy couple at a French Chateau, according to the Daily Mirror.
Kim, 33, and Kanye, 36, have already arrived in Paris to begin preparations for their lavish nuptials.
The pair will reportedly exchange vows in Italy at the 16th-century Belvedere Fort in Florence on Saturday May 24.
But celebrations will begin on Friday May 23 with a lavish dinner and a private tour of Palace of Versailles by night for all their guests. The couple, parents to 10-month-old daughter North, sparked rumours they were planning to tie the knot at the palace when Kim tweeted they had been on a candlelit tour there in January.
Guests will then be flown by private plane to Italy for the main ceremony the next day.
Along with the Kardashian family, the guest list is thought to include Vogue editor Anna Wintour, designers Riccardo Tisci and Donatella Versace and Jay Z and Beyonce.
The wedding - Kim's third - is thought to be costing in excess of £3 million.
