Heather Mills is careful to keep her daughter out of the public eye.

Paul McCartney's ex, who welcomed their daughter, Beatrice McCartney, in 2003, opens up in a new Oprah: Where Are They Now? about making sure her "miracle child" is shielded from celebrity life.

"I rarely talk about my daughter. I'm really proud of the fact that I have kept her image protected," Mills reveals. "She's not mixing in celebrity lifestyles. She's not out in public places."
