Last month, Ellen showed an amazing video of an adorable 4-year-old dancer in China. She loved it so much, she vowed to get him here to perform on the show. Today the adorable YIMING WANG is here from halfway across the world to impress you with his moves! Then, you fell in love with McSteamy on "Grey's Anatomy," now ERIC DANE is in the new movie "Valentine's Day" and will sweep you off your feet! He's here today and he's sure to have some stories from his romantic holiday. Also, RIHANNA recently performed on the show and had such a great time that she's back! She'll sing her song "Rude Boy" and you won't want to miss it! And Ellen's Winter Win Storm is going strong; it's about to get even bigger today when Game Week begins! There's no better game to kick-off a week of huge prizes than Know or Go!
