Rachel McAdams is on the cover of Vogue's January issue, just in time to talk about her new movie Sherlock Holmes. Even though she's a natural working the red carpet, she seems happiest when enjoying some of life's more simple things. She opened up to the magazine about her new green mentality, how she grew up, and her thoughts on relationships. Rachel also talked about working with Lindsay Lohan, years ago on Mean Girls. Here's more:

  • On working with Lindsay Lohan in Mean Girls: "I just remember marveling about how much she knew as an actor, how much she understood. She did very few takes and had this naturalness to her. And beyond that, I was 26 at the time. I’d be asked, ‘Where do you go out?' . . . I felt like I was in a different place at that time."
  • On how going green affects her wanting things: "I don't really desire things. I prefer to spend my money on experiences, on meals or travel. . . I look at the world through a green lens now, but you can't make yourself crazy. That feeling of green guilt can be really inhibiting. It's about a changing mindset, remembering to turn off the water when you are brushing your teeth."
  • On relationships: "I'm pretty good on my own, and I like just getting out and walking, which seems very rudimentary."
  • On how she grew up: "My mother never put an emphasis on looks. She let us grow up on our own time line. She never forced any beauty regimen into my world."
