Kim Kardashian and Kanye West are reportedly planning a $20 million wedding and plan to marry as soon as her divorce from Kris Humphries is made official

Kim Kardashian is reportedly planning a lavish $20 million wedding with Kanye West.

The reality TV star - who has been dating the rapper for eight months and recently returned from a romantic trip to Rome and Venice to celebrate her birthday - is said to be planning to walk down the aisle in a $8.5 million wedding dress as soon as her divorce from basketball player Kris Humphries is made official.

A source told OK! Magazine Kim is already contacting possible wedding planners.

The source said: "Kim is thinking of using David Tutera, who has [worked with] everyone from Jennifer Lopez to Jewel to Barbara Walters."

The 'Keeping Up With The Kardashians' star is also said to be eager for either their close friend Beyonce or Celine Dion to sing at their special day.

The source said: "Kim's all-time favourite singer is Celine Dion, and she has had her people reach out to her for a price; usually a private performance runs well over $6 million.

"Another option they're strongly considering is Beyonce, who will be there anyway.

"Kim's dream dress would have real pearls and white diamonds, like the [gown] designed by Yumi Katsura, which cost $8.5 million."

Kim previously said her next wedding would be very different to her multi-million nuptials with estranged husband Kris.

She said: "It had always been my dream to have a big wedding, and when people said I'd made it over the top for the show, that was just me: I am over the top. But the next time, I want to do it on an island with just my friends and family and that's it."
