As expected, Kanye West canceled a scheduled performance at the Victoria's Secret Fashion show, due to the sudden death of his mother, Dr. Donda West. The producer/rapper was set to take the stage for the event, which will air December 4 on CBS, but backed out, leaving the Spice Girls as the only musical guest.

Dr. West died last weekend in Los Angeles after undergoing an abdominoplasty -- commonly known as a tummy tuck -- and breast reduction. Officials, however, are still unsure whether the surgery caused the 58-year-old's death. An autopsy was performed Tuesday, but a full report will not be available for six to eight weeks, according to the Los Angeles County Coroner's office.

In the meantime, Dr. Jan Adams, who operating on West, is catching flack after a Beverly Hills surgeon admitted to refusing to perform the surgery, due to an undisclosed preexisting condition. Dr. Adams is also said to be in trouble with the Medical Board of California after records of DUI arrests, malpractice lawsuits and a domestic violence-related restraining order have surfaced.
