Lana is currently in the middle of her US tour but will take time out to fly to the wedding this Saturday where she will perform an acoustic track.
The American singer is one of Kim's favourite artists and Kanye originally asked Lana to perform live during the proposal.

She turned him down however, and Kanye instead used a brass band to play Lana's Young and Beautiful as he proposed to Kim in October 2013.
"I can’t get this Lana del Rey song out of my head! #youngandbeautiful." Kim tweeted in the summer of 2013.
The Mirror quoted a source who said: "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."
Kim and Kanye's wedding has been one of the most talked about events of the year, and after months of speculation that the ceremony will take place in Paris, recent reports have stated that guests will instead see Kim and Kanye tie the knot in Florence, Italy.
The reality star and her rapper fiancé are keeping well-wishers and even their guests guessing about the exact details of the celebrations though.
Kim and Kanye are already in Paris preparing for the celebration, and the pair were spotted out and about on Tuesday, stopping off for an ice-cream ahead of their nuptials.
A spokeswoman for the Mayor of Florence has confirmed to the Associated Press that couple would tie the knot in the Italian city next Saturday and said they had rented the fort for 300,000 euros ($410,000). She added that a protestant minister would preside over the ceremony.
Kim's chosen wedding gown will also remain a closely guarded secret until she ties the knot with Kanye, but already Kim is setting trends when it comes to bridal wear.
The beautiful dress she wore on the cover of Vogue for their April issue, featuring a sweetheart neckline and nipped-in waist, has prompted a huge surge in sales in grey wedding dresses on eBay.
