Even though we're well into 2014, it seems Beyoncé Knowles  made a resolution to change up her hair — and she's sticking to it. Last weekend she was sporting a wavy bob at the Grammy Awards , but by Super Bowl weekend she was back to her extralong straight style at a DirectTV Super Saturday performance. Queen Bey is known to switch it up (and stitch it up) often, but two styles in one week! We've got to give credit to her hair team, who must be getting whiplash from the constant makeover. But perhaps the short style is her bad-girl Yoncé personality and this long look is the PG Mrs. Carter persona?
