Jennifer Garner

This brown-haired beauty has come a long way from her role as Sydney Bristow on Alias, turning herself into one of Hollywood's more diverse leading ladies. After small roles in films like Pearl Harbor and Catch Me If You Can, Jennifer quickly garnered (see what we did there?) marquee billing in Daredevil, Juno, and the nutsack-shriveling Ghosts of Girlfriends Past. She's stars in the comedy The Invention of Lying, playing Ricky Gervais' love interest. No wonder she had morning sickness every day during filming.
