How's this for divine inspiration? The fantastic Maura West — a two-time Emmy winner as nutjob Carly Tenney on CBS's As the World Turns — has been cast as the new Diane Jenkins on CBS's The Young and the Restless. West won't be off the air for long. ATWT ends its run September 17 and she'll first appear on Y&R on October 8. She starts taping September 1. Prepare for instant drama: The vengeful, sperm-swiping Diane was once married to mustachioed meanie Victor Newman (Eric Braeden) and was in love with his arch-enemy, Jack Abbott (Peter Bergman), with whom she has a son. The character was played from 2001-04 by Susan Walters, who returned to the role for a two-day stint last February during the Patty-Emily doppelganger mess. (Walters currently plays mayor Carol Lockwood on The Vampire Diaries.) Look for the deets on Diane's storyline and an exclusive interview with La West in TV Guide Magazine.
