Heat magazine claims to have seen a copy of the court injunction banning the press from taking photographs of the axed X Factor USA judge in any private places including her home, her friends' and family's home and buildings not open to the general public.
A supposed friend of Cole's told the publication: "She's not sure she wants anything to do with showbusiness any more.
"She has devoted everything to being famous and she believes it has cost her her health, her marriage and her peace of mind. It's time for a change.
"Cheryl has vowed to put her life back together, and for now that does not include any part of the fame game. She has said she's always making massive changes to her life."

Cole is said to be uninterested in signing any more work contracts and has fallen out of love with public life.
Earlier this month, she stated that she wants to "help young disadvantaged people through my celebrity" in north-east England via her Cheryl Cole Foundation.
The source added: "She said that she felt like her whole life had been bugged - she was being watched every minute of the day.
"Everyone had an opinion on what she was doing, and on her relationships. She just felt it had become too much and was getting to her."
Cole has recently been linked to her ex-husband, Chelsea footballer Ashley, who is said to have told friends that their reconciliation is a "done deal" and was photographed wearing his wedding ring.
However, the England left back was later reported to have been flirting with a blonde woman at a party in Los Angeles.
