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 Kardashian 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.

"She wants to be with him as much as possible. They really know and love each other," the insider said.

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.
