Kim Kardashian and Kanye West ''are talking marriage''.

The couple, who went public with their romance last month (April) are apparently ''very serious'' about making a commitment to each other and are ready to pick out rings.

A source told Us Weekly that the 'Keeping Up With The Kardashians' star and the 'Watch The Throne' rapper - who were friends for many years before they began dating - are more sure than ever about their relationship.

Kim will even be joining the Grammy winner on his summer tour with Jay-Z.

The insider said: ''She wants to be with him as much as possible. They really know and love each other.''

Over the weekend, the 31-year-old reality TV regular jetted back from Washington, DC, where she was a guest at the White House Correspondents' Dinner Saturday, to be by Kanye's side for a Sunday performance of Broadway's 'Wicked' musical.

She has been dating the 34-year-old music producer even though she is yet to finalise her divorce from NBA player Kris Humphries, who she split from last October following 70 days of marriage.
