Casting a former supermodel for a daytime soap appearance doesn’t exactly pack the same punch as James Franco doing General Hospital, but hey, CBS could do a heckuva lot worse than a Czech beauty: has learned exclusively that Paulina Porizkova will do a multi-episode arc on As the World Turns beginning Jan. 5. She will play a character named Clarissa who has a history with Simon Frasier (Paul Leyden). ATWT averages 2.52 million viewers.
