Being famous comes with its perks and disadvantages.

Actress Anne Hathaway revealed during an interview for Elle U.K.'s November issue that she had a difficult time dealing with fame.

"This fame thing? F--ked me up for a really long time," the 31-year-old actress said. "I didn't know how to do it; I didn't know how to engage with it; it stressed me out. And people would say, 'You just have to be yourself,' and I was like, 'But I don't know who that is yet!'"

Hathaway received a lot of criticisms - for her fashion and acceptance speeches - after winning an Oscar for "Les Miserables." At the time, she decided to take a break from the Hollywood spotlight.

"I've realized that I don't need validation from anybody," she told Elle U.K. "At all. I'm not sitting here now worrying, 'What do you think of me?' With all due respect," she said, addressing her interviewer, "you seem like a lovely lady, but I don't need you, or anyone else, to like me. And that's so liberating."

During her time off, the "Ella Enchanted" actress, who got married to Adam Shulman in 2012, has been focusing on her married life. Hathaway admitted that her first year of marriage "was insane."

"So much happened so fast, and we didn't get to focus on just being married until about a year in," she revealed. "So now, it's just about letting myself feel safe. There was a part of me that I was keeping in reserve, and when I got married, something shifted...That question of, 'How long's this gonna last?' is off the table. And when you're not worried about that, there's space to just be silly."

Hathaway will return to the big screen in "Interstellar," and will star opposite of Matthew McConaughey, Jessica Chastain and Michael Caine. The film was directed by Christopher Nolan and will hit theaters on Nov. 5.
