You really can't just take someone who's got a drug addiction and just put 'em in rehab. It doesn't work that way. You can't choose it for them. They have to choose it for themselves - because that's scary. It's really hard.

From Marilyn Monroe and beyond, that's a huge part of Hollywood, creating a persona that's mysterious and fairly simple, though it's interesting how that's changing: Now, you have fans who are like, "Um, yeah, I just emailed with Barack Obama and tweeted with Lady Gaga, so I'm kinda right there with you; give it to me."

I really like Twitter. It's a conversation and it reminds me of having stranger conversations on the train. I'm a New Yorker. I'm used to bumping into strangers, acknowledging them, them acknowledging me, even if it's just with an eyebrow lift.

This is the only free country in the world that's doing lobbying. Voters should be the lobbyists. If we can spend all of this time with all these different celebrities who fill up the internet and magazines then we should be able to keep an eye on politicians because they might cost you your job and your home and your life savings.

I'm in high heels, I'm wearing a fabulous dress, people want me to just smile and talk about my movie because I only have three minutes, and that's my job.

It's a form of violence, in the way that we look at women and how we expect them to look and be - for what sake? Not health, not survival, no enjoyment of life but just so you could look pretty. I'm constantly telling girls all the time, 'Everything's airbrushed, everything's retouched. None of us look like that.

When I see a woman who is all gaunt and emaciated, I don't think she's beautiful. She reminds me of a Chihuahua that's freezing and shaking.
