The 18-year-old, who finished fourth on the show in 2010, tells heat magazine this week that she's never been after fame.
“I’m not your average celebrity. I’m not a celebrity. I never ever will be," the 'Swagger Jagger' singer explained. "I’m not someone to get out of a cab with my drawers on show. I’m here to make music. [Emphatically] I am a businesswoman.”
She added: “I’m in this to make a good life for myself”.
Cher, who got engaged to boyfriend of 6 months Craig Monk in December, also revealed that she is refusing to make her personal life public.
"Basically I had a really good word with myself today and I’ve come to a decision," she told the magazine. "This is the last time I’m ever going to talk to anyone about my love life, because I just feel like people are getting chunks out of me. I don’t feel like me anymore. I just feel like a stupid cardboard cut-out.”
“People are negative no matter what you do. People are always going to say, 'She’s too young.' I’m from a Gypsy background! I’m meant to be married by now.”
Cher continues: “I’m happy, really happy. I love him to pieces, more than anything in the world, but I don’t want people to take that away from me.”
