Katy Perry was all about blue on the red carpet at this evening's Grammys. She paired her bright colored hair with a similarly-hued dress from celeb favorite Elie Saab. Katy's up for two honors this evening. "Fireworks" is in contention for record of the year and she's also up for best pop solo performance. We'll see if Katy gets her hands on her first Grammy, as she's been nominated — for six previously — but hasn't won. She's especially excited for one of the show's performers. Katy tweeted earlier this afternoon, "You know it's a great day when you walk into the Staples Center and all The Beach Boys are physically playing on stage." Weigh in on Katy's look, as well as all of the others, with our love it or hate it polls!
