One of Ellen's all-time favorite kids is back! The incredibly talented EMILY BEAR will update everyone on what she's doing, and will treat us all to an amazing performance at the piano. She's composed new songs just for Ellen, so you'll want to see what she brings this time! Then, she won an Academy Award for her role as the Queen of England, now HELEN MIRREN is playing the wife of Leo Tolstoy in the new movie, "The Station." It's her first time on the show, so Ellen will make sure she doesn't forget it! Also, you've been hearing the hit song "TiK ToK" for months, but you may not know who sings it. It's the first single from KE$HA, and her debut CD, "Animal," is out today. To celebrate, she's here to perform for everyone.
