Kim Kardashian and Kanye West have asked Lady Gaga to sing at their wedding.

The couple - who have a seven-month-old daughter North - are expected to marry in Paris, France in the summer and it is said they are keen to have the "Applause" hitmaker perform at the upcoming nuptials.

"Kim and Kanye met up with Gaga in Paris. They were desperate to get the star's involvement, which is why she's the first person to be asked. She's ideal for them because Kanye has always been a fan of her style and performance art. But also, Kim loves her music, so it's one they can instantly agree on," a source said.

The two stars will have to keep searching for a venue for the wedding though, after they were deemed "not classy" enough to get married at the Palace of Versailles. "Kim and Kanye really wanted to get married at Versailles and were hoping to persuade officials during their visit. But ultimately it backfired. It was still a firm non. They will now be scouting private estates and chateaux in the region," an insider said.
