Kristen Bell has been positively glowing on the last couple of occasions that we've seen her on the red carpet, and I have a sneaky suspicion that it has less to do with her rosy blush and a whole lot more to do with her recent engagement to Dax Shepard. Funny how love can make hair just 'work' isn't it? We saw her at the Grammys yesterday wearing her hair down and loose, while last week, at the Hollywood premiere of her new flick, When In Rome, she opted for a pretty braided bun. Both look amazing, but which look is your favourite?
