Kanye West has agreed with estranged wife Kim Kardashian West's request that they share joint custody of their four children.

Lawyers for the superstar rapper and billionaire fashion mogul filed a response at Los Angeles Superior Court, mirroring Kardashian West's filing from February.

The legal papers, obtained by the PA news agency, cite irreconcilable differences as the reason for the split.

West, like his former partner, is requesting joint custody of North, seven, Saint, five, Chicago, three and one-year-old Psalm.

Kanye and Kim in happier times

He did not list a date of separation. The Wests' relationship had been subjected to months of speculation before divorce papers were filed.

West, 43, also agreed with Kardashian West's request for the court to terminate its ability to award spousal support.

Both parties are billionaires, according to Forbes magazine.

Kardashian West, 40, filed for divorce on February 19 and revealed she and West had a pre-nuptial agreement in place.

They tied the knot at a lavish ceremony in Florence back in May 2014.
