The Grammy nominations are out -- and KATY PERRY is up for Album of the Year! She's here to celebrate the honor and to sing her new hit song, "Firework." It's Day 5 of Ellen's 12 Days of Giveaways -- and that means you have more chances to win from home! Be sure to follow Ellen on Twitter and Facebook for an extra shot at winning! If anyone knows how to stay classy, it's HELEN MIRREN! Whether she's accepting an Academy Award, lounging in her own castle, or being photographed on the beach -- she always makes it look good! Dame Helen is stopping by today to chat with Ellen.
