There aren't many artists having a bigger year than PHARRELL WILLIAMS... or sporting a bigger hat! The six-time Grammy winner returns to Ellen after topping Billboard charts with hits like Daft Punk's "Get Lucky," Robin Thicke's "Blurred Lines," and ... (more)the ubiquitous "Despicable Me" anthem, "Happy." Everyone is feeling his joy these days! With a brand new, critically acclaimed album called "Girl," Pharrell will make Ellen's stage feel like a room without a roof! She's pretty much the cutest thing in Hollywood, ZOOEY DESCHANEL is here! All eyes are on every skirt, shoe and nail polish the "New Girl" star flaunts, and thankfully, she's lending her imaginative style to Tommy Hilfiger with a new line of dresses called "To Tommy, From Zooey." Really, it's a gift to the rest of the world. It's hard not to giggle, grin and play with life when Zooey's around. Ellen is so excited for the beautiful star to join her again! Plus, CHADWICK BOSEMAN meets Ellen for the first time! After breaking out in "42," Hollywood's big-screen take on Jackie Robinson, the actor continues to play the field like a champion, now starring in the upcoming football film "Draft Day." Chadwick brings his A game when he stops by the show! On Thursday, Ellen's clapping along with happiness!
