Cheryl Cole repackages things she has been given for free and gives them away as gifts to other people.
Simon said: "Whenever you go to an event and you get a bag of freebies, Cheryl repackages them and gives them to somebody else. I always give mine to charity."
Simon also branded Cheryl "narcissistic" after previously accusing her of copying the 'salute' gesture he used to do for fans.
He added to Syco: "We've established that she won't be copying my salute anymore. She says it's a salute to Cheryl's Army, which is so narcissistic! I don't think she realises how insane that sounds."
Cheryl isn't the only 'X Factor' star to pass on the freebies she is given because of her celebrity status.
She said: "I get so much gorgeous stuff. I'm slightly bigger than her, so if she gets something a bit big, she'll give it to me, and if I get something too small, it goes her way."
