Rapper Kanye West recently visited his mother's grave in Oklahoma with girlfriend Kim Kardashian.

"Kanye brought Kim to Oklahoma City the day after Thanksgiving to pay respects to his mother (Donda West) and to meet his mother's side of the family. This was her first meeting with them," showbizspy.com quoted a source as saying.

"This was a really monumental moment for Kanye because he adored his mother. He wouldn't have brought Kim unless he was completely in love with her," added the source.

The 35-year-old rapper's mother died Nov 10, 2007 of complications from cosmetic surgery. She was 58.

West has reportedly promised Kim that he will marry her as soon as her divorce from basketball player Kris Humphries comes through.

The couple celebrated Thanksgiving with Kardashian family on Thursday before flying to Oklahoma together Friday.
