Emma Watson has hit back at critics who claimed her decision to pose topless was hypocritical given her feminist stance.
The Harry Potter actress triggered a backlash when she was photographed for Vanity Fair magazine wearing a jacket with nothing underneath.
Some commentators said Watson, 26, had gone against what she stood for and accused her of being anti-feminist.
But she told the BBC: "Feminism is about giving women choice, feminism is not a stick with which to beat other women.
"It's about freedom, it's about liberation, it's about equality."
Watson went on: "I really don't know what my tits have to do with it."
The actress was being interviewed alongside Dan Stevens, her co-star in Beauty And The Beast.
When he asked what she was discussing, the actress explained: "They were saying that I couldn't be a feminist and... and have boobs."
She said she always found herself "quietly stunned" at such comments.
Watson was photographed for Vanity Fair by British fashion photographer Tim Walker.
The actress was wearing a chunky open-weave bolero jacket with nothing underneath, but the high-fashion picture was cleverly crafted to protect her modesty.
Many fans applauded the shot, but others suggested it undermined Watson's feminist credentials.
Broadcaster Julia Hartley-Brewer was among those to comment, tweeting: "Emma Watson: 'Feminism, feminism... gender wage gap... why oh why am I not taken seriously... feminism... oh, and here are my tits!'"
