While we all now know Katie as Mrs Cruise and mother to style icon Suri, she first became famous for her part as the ultimate girl-next-door Joey Potter in Dawson's Creek. Even though the script was cringe and the constant swapping of partners was annoying, we still loved this show! Katie's character was known for her jeans and baggy jumpers...a long way from the chic A-lister we now know and love.
