Nigel Lythgoe, a longtime producer and judge on "So You Think You Can Dance," has voluntarily stepped down from the show after being sued by Paula Abdul for alleged sexual assault. Lythgoe denied the accusation and expressed his dedication to clearing his name. The show will continue without him, with new judges joining for the upcoming season. This follows Abdul's lawsuit accusing Lythgoe of assaulting her during their time working on "American Idol."
