Lana Del Rey reportedly will perform at Kanye West and Kim Kardashian's wedding. A source told Hollywood Life the 27-year-old musician has agreed to sing at Kimye's May 24 ceremony in Europe. "Lana is performing at Kim and Kanye's wedding," the person confirms. "She's in the middle of her U.S. tour and is taking time out to perform. She may be performing an acoustic song, something really classy." Kardashian is a fan of Del Rey, and an orchestra played "Young and Beautiful" during West's surprise proposal in October. The singer is said to have turned the rapper down when he asked her to perform the song live for the engagement. The Mirror reports Del Rey will be paid six figures for her appearance at the wedding. "He upped the offer to perform at the wedding and told Lana that ['Young and Beautiful'] is his and Kim's special song," a different source tells The Mirror. "She couldn't say no." Del Rey announced last week that her new album, "ULTRAVIOLENCE," is set for release June 17.
