Rizzoli & Isles‘ star Sasha Alexander is taking a risque turn with a major recurring arc on Season 5 of Showtime dramedy Shameless. She will play Helene, one of Lip’s (Jeremy Allen White) college professors, who’s erudite, confident and sexy with a wild side. The role is definitely new territory for Alexander compared to her more sedate character on TNT’s Rizzoli & Isles as Dr. Maura Isles, the Commonwealth of Massachusetts’ Chief Medical Examiner, working at the Boston Police Department. Alexander is repped by UTA, Circle of Confusion, and Felker, Toczek, Gellman, Suddleson. Shameless is executive produced by John Wells, Andrew Stearn, Christopher Chulack, Davey Holmes and Nancy Pimental.
