It's been six long years since BRUCE WILLIS has been here, but today he's back! He's still as big an action star as ever and is taking a minute to chat with Ellen about everything that he's been up to. Ellen's WB neighbor and fellow ping-pong enthusiast KALEY CUOCO is back to work after her recent horseback riding injury. Ellen will make sure Kaley is comfortable when she stops by today. JOSHUA RADIN sang for Ellen and Portia at their wedding, and today Ellen is excited to see him again as he premieres a song from his brand new album, "The Rock and The Tide."
