Last week, America was shocked when PIA TOSCANO was voted off "American Idol" -- including Ellen! Pia is an incredibly talented singer and Ellen wanted to get her on the show. Today Pia will talk about her controversial elimination, and sing for everyone!

KATE WALSH knows how to keep busy! Not only is she starring in the hit show, "Private Practice," she also created her very own fragrance, Boyfriend, completely on her own! She's making some time to visit, and will tell Ellen what she's been up to.

The hilarious PAUL REISER was nominated for an Emmy an incredible ten times for his hit show, "Mad About You." Now, after more than a decade, he's finally returning to television with a brand new show -- and that means he's returning to visit Ellen!

A few months ago, Ellen met speed-rapper GEORGE WATSKY when he impressed everyone with his skills. She loved him so much, he's back today to perform another one of his original raps.
