Kimye don't get everything that they want! Kanye West requested Lana Del Rey to sing at his proposal to Kim Kardashian but she declined, turning him down flat.

Kardashian is a huge fan of LDR and loves her track 'Young & Beautiful' from 'The Great Gatsby' soundtrack. Yeezy asked the singer to participate in the engagement spectacle, which took place at AT&T Park San Francisco on the reality star's 33rd birthday on Oct. 21.

A source told Radar, "Lana politely declined, and didn’t give any reason for not being able to perform. It was a very firm no from Lana and her camp."

At first, the rapper didn't take a very firm no for an answer, with the insider saying, "Kanye did try to push it, but didn’t get anywhere. Kanye decided to hire an orchestra to perform the song for Kim, and he was much happier with how it turned out."

Or was he just happier with it since his first choice wasn't interested in the gig?

For her part, Kimmy was "bummed that Lana didn’t perform for the big event, but she is still a huge fan." Plus, it was the thought that counted for her when it came to her fiance's idea.

The source said, "She just loved that Kanye tried to make it happen. Kim is jokingly saying Lana will want to perform at their wedding."

Or not.
