Despite her sweet and down-to-earth image, Anne Hathaway says she has behaved badly in the past.
"You know, Lindsay [Lohan] and I have a lot more in common than people think," she says in an interview with the UK's The Sunday Times.
"We've all done things we shouldn't, it's just I did stuff at college, when nobody knew about it, so I'm not a saint."
The Devil Wears Prada
actress says of Lohan, who entered rehab last month: "Lindsay's a nice girl, I like her a lot, and she's a great actor, but there's a fascination about her lifestyle that distracts from her talents. I just hope she finds some comfort in the way she chooses to live."
But according to Hathaway, 24, she went through her own hard-partying phase. "I wasted time doing self-destructive things but it didn't work. I found out you can only dance on so many tabletops. I got that all out of my system and now I'm healthy and I'm grounded.
"I had to work through some s--- in my personal life," Hathaway explains. "I wasn't ready to be a serious actress, with all that entails, because I still had a lot of questions about myself as a human being."
Hathaway – who recently admitted she battled depression
– dates her turnaround to three years ago, when she met her boyfriend, Italian property developer Raffaello Follieri, 27.
"He's brought out so many positive attributes," she says. "Before I met him, I wasted so much time. I was just annoying and narcissistic and smelled bad. He's protective without being possessive, passionate without needing to show his temper."
