Tracey as Laura Bush

She's baaa-aack! The queen of impersonation, Tracey Ullman, returns with 'State of the Union' to give us a quick view into the worlds of the famous and not-so-famous. You'll see the reappearance of familiar faces, including Arianna Huffington and Renée Zellweger, and some new stars added to the mix (J.K. Rowling and Celine Dion). Check out photos of the many faces of Tracey Ullman from the new season!
