ABC News' Paula Faris and Amanda Keegan report:

Scarlett Johansson has gotten used to the red carpets, movie premiers and dealing with some of the unwanted attention that comes with A-List celebrity status, but the star admits she is "paranoid" after nude photos of her landed on the Internet last year.

"When all those photos came out, of course I go out to dinner and think, 'Goddamn it, these people have all seen my. . .'," the 27-year-old actress told Vogue magazine. "You can't not think that. Even if they haven't, you're paranoid."

"The Avengers" star opened up in Vogue magazine's May cover story, revealing how just much she was affected by the Sept. 2011 hacking and photo leak.

Nude photos of Johansson, which were intended for former husband Ryan Reynolds, were hacked from her email account and quickly spread across the internet. Her hacker, who authorities learned had also tapped into the emails of stars such as Christina Aguilera and Mila Kunis, plead guilty last month to stealing the images.

"I don't want to be a victim and say, 'Oh, well' and just hide my head in shame. Somebody stole something from me. . . . It's sick. I don't want people like that to slide," she told Vogue.

Johansson immediately alerted authorities and her legal team moved swiftly, threatening to sue sites that posted the pictures online.

"Scarlett Johansson is a profile of courage," said longtime publicist and ABC News consultant Howard Bragman. "She went and she made sure that this man was convicted this heinous crime and that he won't do it to anyone else, and I think it is a great example to celebrities and anyone."

The leak came at an inopportune moment for Johansson, just months after her public divorce from Ryan Reynolds, a split that she tells Vogue was "comically amicable," but still "devastating."

"It was horrible. Of course it's horrible," she said in the Vogue interview. "It really throws you. You think that your life is going to be one way, and then, for various reasons or whatever, it doesn't work out.

"And there's no way to navigate it. Nobody can give you the right answer. It's never anything you want to hear. It's a very lonely thing. It's like the loneliest thing you'll ever do, in some way," she said.

But now, Johansson has a new man on her arm, advertising director Nate Naylor, and the blockbuster movie, "The Avengers," about to debut, and says she has finally found a "relative peace."

"From that comes a lot of really amazing things," she told Vogue. "I think it will be an interesting year."
