What She's Done: From playing Lindsay Lohan's ditzy frenemy in 'Mean Girls' to Meryl Streep's ABBA-singing daughter in 'Mamma Mia!', Seyfried has pretty much done it all. And moviegoers seem to like what she's doing, as evident this year with the release of 'Dear John,' the film that officially dethroned 'Avatar' as king of the box office.
What's Next: She'll team with 'Twilight' director Catherine Hardwicke on the gothic thriller 'Red Riding Hood' and Justin Timberlake in an untitled thriller from 'Gattaca' director Andrew Niccol.
Did You Know? Seyfried reportedly auditioned for the title role in the TV series 'Veronica Mars,' on which she eventually played Veronica's (Kristen Bell) dead best friend, Lilly Kane.
