For 8 years, we've watched her light up the screen on "Desperate Housewives," and now MARCIA CROSS is at the start of the epic final season of this groundbreaking show. She's seen it all; the good, the bad and the incredibly good-looking, and she's here to tell Ellen what we can expect from the show that's kept everyone guessing.

LAUREN ALAINA had America on the edge of their seats from the first auditions of last season's "American Idol," all the way through to the big finale. This outrageously talented 16-year-old singer will tell Ellen about her incredible adventure on the show that made her a star, and of course, will perform her song "Georgia Peaches" from her upcoming debut CD, "Wildflower."

Plus, Ellen's Swaggin' Wagon is surprising another deserving family right in their driveway. It could be yours!
