For the first time, the hilarious SETH ROGEN is here! He just got engaged to his girlfriend this fall -- and Ellen is going to find out all about their marriage plans! She'll also find out about his brand new action movie, "The Green Hornet."

The "Jersey Shore" house has a brand new member this season: DEENA NICOLE CORTESE. The self-described "blast in a glass and party in a body" is stopping by to tell Ellen what it was like to join the New Jersey crew.

When BRUNO MARS was here recently, he gave such a great performance that Ellen had to have him back! Today he's here to perform a special version of his hit, "Just the Way You Are."
