Rachel McAdams practices what she preaches. Not only does she have an adorable environmental activism website with her friends, but she's committed to her bike riding through and through. Rachel is at home in Canada rocking out to her iPod, but pretty soon she'll be back on set alongside Eric Bana for The Time Traveler's Wife, a book that is near and dear to many people's hearts (including my own). McAdams is wearing a ring on that ring finger, though I do doubt it means anything since I've accepted that she and Ryan broke up months ago. I'm not holding my breath for that reunion anytime soon, but I am excited to see Rachel back on the big screen this winter.
