Happy Birthday, Amanda Seyfried! See Her Most Stylish Roles

Happy birthday! Amanda Seyfried turns 31 today and she has a lot to celebrate. She recently became engaged to her co-star from The Last Word, Thomas Sadoski, debuting a refreshingly minimalist ring on her left hand. Earlier this week it was also confirmed that the two are expecting their first child together. The Mean Girls star and mom-to-be introduced her growing baby bump (and enviable maternity style) to the world wearing an LBD to a Givenchy event.

To celebrate the start of another big year for the actress, let's take a look back at Seyfried's most stylish roles to date. From the lovable and quotable Karen Smith in her breakout role in Mean Girls to her diverse lineup as characters in Westerns, thrillers, fantasies, and quirky comedies, Seyfried has had an impressive career. Next year is looking to be full of great changes for the star, and we're excited to seeing what's to come for her in 2017.
