Los Angeles, May 9 : Socialite Kim Kardashian and rapper Kanye West's wedding planning is on in full swing, but the couple can't get married yet as their pre-nuptial agreement is still to be signed.

Source close to the duo have told tmz. com that the pre-nuptial agreement won't be signed until next week.

If sources are to be believed, unlike Kardashian's pre-nuptials with former husband Kris Humphries, the current negotiations are friendly.

The matter has just got a little complicated as West recently changed management.

The rapper is set to exchange vows with the "Keeping Up With The Kardashians" star May 24 in Paris.(IANS)
