Julie, 89, passed away on Sunday.
The X Factor boss tweeted: "My family lost someone very special on Sunday. My Mum. I am overwhelmed with gratitude for all of the kind messages received. Thank you. X"
A family spokesman broke the sad news on Monday 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.
"We would like to thank the media for kindly respecting Julie's privacy throughout and we politely request continued privacy for the entire family at this particularly difficult time.”
