Donda West, mother of hip-hop star Kanye West, died Saturday in Los Angeles following a "cosmetic procedure." She was 58.

Dr. Donda West retired from her position as chairwoman of Chicago State University's English department in 2004 to help manage her son's career. She went on to head the Kanye West Foundation and West Brands LLC.

In May 2007, she penned the memoir 'Raising Kanye: Life Lessons From the Mother of a Hip-Hop Star' in which she discusses raising the producer-turned-rapper as a single parent and her experiences as his manager.

The rap star has been extremely vocal about his close relationship with his mother, honoring her with the song 'Hey Mama' from 2005's 'Late Registration.' Read the full story.
