Jennifer Lawrence says the people who leaked naked photos of her online are guilty of a sex crime.
Dozens of private pictures of the Hunger Games actress were released on the web in September.
Speaking to Vanity Fair, the 24-year-old said: "It is not a scandal. It is a sex crime. It is a sexual violation. It's disgusting.
"The law needs to be changed, and we need to change. That's why these websites are responsible."
Other celebrities targeted in the first wave of leaks included Rihanna, Kate Upton, Selena Gomez and Kim Kardashian.

It's thought the photos were taken off the stars' iCloud accounts and were shared on websites such as Reddit and 4chan.
Google said last week that it had removed "tens of thousands" of nude pictures stolen from celebrities.
That was after Hollywood entertainment lawyer Marty Singer threatened to sue the tech company for "violating privacy".
Jennifer Lawrence says she certainly didn't give anyone permission to look at her body.
"Just the fact that somebody can be sexually exploited and violated, and the first thought that crosses somebody's mind is to make a profit from it. It's so beyond me," she said.
"I just can't imagine being that detached from humanity.

"I can't imagine being that thoughtless and careless and so empty inside.
"Anybody who looked at those pictures, you're perpetuating a sexual offence. You should cower with shame.
"Even people who I know and love say, 'Oh, yeah, I looked at the pictures.' I don't want to get mad, but at the same time I'm thinking, 'I didn't tell you that you could look at my naked body'."
Apple confirmed last month that some celebrities' iCloud accounts were hacked but said there was no evidence it was caused by a breach of its security systems.
Lawrence said she was gutted when she found out about the leak of nude photographs.
"I was just so afraid," she admitted. "I didn't know how this would affect my career.
"Just because I'm a public figure, just because I'm an actress, does not mean that I asked for this.
"It does not mean that it comes with the territory. It's my body, and it should be my choice, and the fact that it is not my choice is absolutely disgusting.
"I can't believe that we even live in that kind of world."
A spokeswoman for the actress issued a statement at the time saying she was going to sue over the photo leak.
She said she'd been tempted to write a statement herself but that everything she tried to write made her "cry or get angry".
"I started to write an apology, but I don't have anything to say I'm sorry for," she said.
"I was in a loving, healthy, great relationship for four years. It was long distance, and either your boyfriend is going to look at porn or he's going to look at you."
Jennifer Lawrence, who's also starred in American Hustle, X-Men and Silver Linings Playbook, says the worst bit about the whole affair was having to tell her father.
"I promise you, anybody given the choice of that kind of money [for Hunger Games] or having to make a phone call to tell your dad that something like that has happened, it's not worth it," she said.
"Fortunately, he was playing golf, so he was in a good mood."
