Simon Cowell's mother Julie Cowell died Sunday at the age of 89.
In the wake of her passing, X Factor U.K. auditions scheduled to begin Monday in Manchester have been canceled. "They were due to start today and carry on into Tuesday and Wednesday," a Syco Entertainment spokesman said in a statement Monday. "Today's have been cancelled and we have not made any decisions beyond that."
A spokesperson for the Cowell family announced her death Sunday night, saying, "Today our beloved mum Julie passed away. Anyone who had met her would know what a truly special and kind lady she was. We are heartbroken and will miss her terribly, but she is now at peace."
