Today, one lucky person will win a huge prize that will leave them speechless! Everyone is a winner today when SAMUEL L. JACKSON stops by. He's one of the biggest celebrities ever -- his movies have grossed more money than anyone else's! He's played some fantastic roles and is the King of Cool, but he knows how to stay grounded; he even loves seeing his own movies with regular movie fans! Now, he's starring in one of the biggest movies of the year, "Iron Man 2." Then, everyone is talking about the smash hit, "Glee." It turned LEA MICHELE into an overnight star, and in the past few months, she sang at the World Series and was invited to perform at the White House by Michelle Obama! Now she gets to sit with Ellen and share all the excitement. Also, Ellen can't stop listening to the new band, GRACE POTTER & THE NOCTURNALS. Rolling Stone declared them the Best New Act of 2010, and Ellen wants to share them with you. They'll sing their song, "Tiny Light."
