X Factor judge Sharon Osbourne has talked about her fight against an eating disorder called bulimia which affects loads of young people.
Sharon has been suffering from bulimia since she was a teenager and she told The Sun newspaper that she still goes on eating binges and makes herself ill.
The 52-year-old said: "It's bad, but I'm really trying to get better."
Sharon used to make herself ill four times a day. She said the disorder was about "having low self-esteem".
She revealed that she visits a therapist every week to help control her eating problems.
Sharon, who has already beaten cancer, said her husband, Ozzy, and her three children were worried about her.
The family became household names after appearing in their own reality TV show.
