“Photos from a clothes fitting Emma had with a stylist a couple of years ago have been stolen. They are not nude photographs. Lawyers have been instructed and we are not commenting further,” her publicist said in a statement to Variety.

Social media and blog posts have claimed that naked images of Watson have been posted this week on an anonymous document-sharing network. It was not clear what action her lawyers are planning, or against whom.

Watson, 26, who made her name as a child star playing Hermione Granger in the Harry Potter movies, found herself at the center of a social media controversy earlier this month over a photo shoot she did for Vanity Fair magazine that included a picture in which parts of her breasts were exposed.

Critics called Watson, who is also a United Nations goodwill ambassador on women’s rights and equality, hypocritical and said she was betraying her feminist ideals.

Watson hit back, saying feminism was about choice. “It’s about freedom, it’s about liberation, it’s about equality. I really don’t know what my tits have to do with it,” she told Reuters.

Watson appears in the live action version of the Disney classic Beauty and the Beast, which opens in movie theaters around the world this week.
