Katherine Heigl
Katherine Heigl’s most famous role to date was as Isobel Stevens on the medical drama “Grey’s Anatomy. But she reportedly questioned the scripts and made edits without permission. She was also allegedly horrible to the show’s production assistants. But despite claims that she was let go from the show, Heigl later said the reason she quit was because she was a first-time mother and no longer wanted to work full-time. But despite some failed attempts to jumpstart her career, she is now starring in the hit Netflix series “Firefly Lane.”
