Hollywood star Angelina Jolie has begun to fear the day when her children with Brad Pitt would ask her about her wild days.

According to OK magazine, in an interview with Anderson Cooper, Jolie said was not sure whether she could be a good mother.

Anderson initially asked her whether she was wild when young.

"I didn't know if I'd ever be a mother, be a good mother, I was nervous. When I was younger I thought, oh god, I couldn't be somebody's mother, I think we all thought that," Angelina was quoted by OK, as saying.

Jolie, who is now a mother of six, confesses that when her children approach her and ask what she had in mind back then, she will have to tell them the truth.

"I just know it's going to come back at me very soon with my children," she said.

Cooper then asked her, "How you will deal with your children when they will become a teenager and you will try to discipline them, but they will say 'Uh ... you used to wear blood around your neck'?"

Angelina said, "Yes, I did."
