Kristen Stewart posed for pictures at the 2012 Nickelodeon Kids' Choice Awards this evening, and she looked absolutely stunning in this blue lace Stella McCartney dress.

It also seems like this was her lucky outfit, as she walked away with the award for Favorite Movie Actress award for her role as Bella in The Twilight Saga: Breaking Dawn – Part 1! While accepting her award, Kristen admitted that it was her first time at the KCAs, adding, "This is, like, the coolest award show ever."

What happened to the nervous slash awkward starlet who dropped her MTV Movie award a few years ago?!
