Kanye West took Kim Kardashian to visit his mother's grave.

The 'Mercy' rapper - who has been dating the 'Keeping Up With The Kardashians' star for eight months - was spotted visiting his mother Donda West's graveside in Oklahoma with his 32-year-old girlfriend on Friday (23.11.12) and later visited other family members in the area.

A source told gossip website RadarOnline.com: ''Kanye brought Kim to Oklahoma City the day after Thanksgiving to pay respects to his mother and to meet his mother's side of the family. This was her first time meeting them.''

The 35-year-old rapper's mother died on November 10, 2007 of complications from cosmetic surgery at the age of 58.

Another insider suggested the trip is proof the couple are heading towards marriage, saying: ''This was a really monumental moment for Kanye because he adored his mother.

''He wouldn't have brought Kim there unless he was completely in love with her.''

Kanye is rumoured to have given Kim a promise ring and wants to marry her as soon as her divorce from basketball player Kris Humphries is official.

The couple celebrated Thanksgiving with Kim's family on Thursday (22.11.12) before flying to Oklahoma together.
