Anne Hathaway has ''wasted time'' being self-destructive.
The 'One Day' star insists she is very similar to troubled actress Lindsay Lohan - who has been to rehab and jail numerous times and experienced a string of legal problems - but she was lucky enough to be able to live out her mistakes in private.
She said: ''Lindsay Lohan and I have more in common than people think. We've all done things we shouldn't.
''It is just that I did stuff at college when nobody knew about it, so I'm not a saint. I wasted time doing self-destructive things.
''I found out you can only dance on so many table tops. I got all that out of my system and I am healthy and grounded.''
In 2008, Anne's ex-boyfriend Raffaello Follieri was arrested and subsequently jailed for fraud and the 29-year-old beauty - who is now engaged to actor Adam Schulman - says the experience taught her to maintain a sense of humour when dealing with adversity.
'The Dark Knight Rises' star added in an interview with The Sun newspaper: ''I try to keep my personal life low-key, particularly after what happened to me. As I say, I do need to keep a sense of humour...
''You need to hold on to that sense of humour. I've been in so many embarrassing situations over the years.''
