Kanye West's mother, Donda West, passed away this Saturday in Los Angeles at age 58. A cause of death has still not been released. Donda was the chief executive of West Brands LLC, the parent company of Kanye's business enterprises, and she chaired The Kanye West Foundation. Donda recently published a book about her son entitled "Raising Kanye: Life Lessons from the Mother of a Hip-Hop Star."

This is very sad news, especially knowing how close Kanye was with his mother. She is mentioned in nearly all of his songs, most notably the track "Hey Mama." Click below to listen.

Update: Sadly, it has been confirmed that Donda West passed away due to "complications from a cosmetic surgical procedure." Kanye was notified of his mother's death upon arriving in London and immediately returned to Los Angeles to be with family members.
