Victoria Beckham "wouldn't wish" her schooldays on anyone.
The 39-year-old fashion designer admits she wept when she received a British Fashion Award two years ago because she couldn't believe how much her life has changed since she was bullied for being "different".
She said: "I had come such a long way. I didn't go to a private school; it was a public school. It was not a very nice school.
"[I was bullied because I was] different from all the other children at the school. I really wouldn't wish it on any kid, because it's horrible."
Victoria - who has children Brooklyn, 14, Romeo, 11, Cruz, eight, and Harper, two, with husband David - credits her former Spice Girls bandmates for helping her overcome her problems and become more confident.
Speaking to the new edition of Allure magazine, she said: "I think what gave me confidence in myself was meeting the other girls. We always said we were all like rejects in our own way. We had to work hard, and they helped me accept me for who I was."
And the British star also admitted to having "purchased" her breasts, though she has now had the implants removed.
Looking at an old photograph, she said: "I don't have them anymore. I think I may have purchased them."
