Gina Gershon is most famous for her risqué roles in movies like Showgirls and Bound, but her career has brought her into contact with all manner of stars from the worlds of film, theater and music. In her new book, AlphaPussy (out now), Gershon, 63, looks back on the twists and turns her life has taken, with plenty of famous faces making cameos. Younger fans who recognize her as Jughead's mom from Riverdale, for example, may be surprised to learn that Gershon has a robust theater background.
