The hilarious KIM CATTRALL made a name for herself as Samantha, the no-holds-barred and sometimes controversial character on "Sex and the City." She's not shying away from the scandalous roles -- now she's playing a former porn star in "Meet Monica Velour," and is dropping by today!

The sexy TIMOTHY OLYPHANT has a lot to celebrate... his show, "Justified," was just renewed for another season! Ellen will have the champagne ready when he visits today.

RALPH MACCHIO has traded in his black belt for dancing shoes! The original "Karate Kid" actor joined this season of "Dancing with the Stars" and he's stopping by with dance partner KARINA SMIRNOFF to chat with Ellen -- and perform a routine just for her!
