The 40-year-old star said she got the revenge on her bullies by living a happy life, Female First.
"I was kind of bullied when I was younger, actually at school. For being chubby, you know, I had girls who were envious of me because I was acting a little bit as a teenager," Winslet said.
"This (being happy) is my revenge. Right here, this lovely career I have been blessed with. I have healthy children. You know, I have a really happy life and, to me, it's like, 'Well, look at me now girls!'" she added.
