One of Kianna Underwood's "All That" castmates tried to muster help for the down-and-out former Nickelodeon child star years before a hit-and-run driver killed her in Brooklyn -- as sources revealed Monday that police found the car behind the horrific crash. Angelique Bates posted an emotional Instagram video in November 2023 alerting her fellow "All That" alums that Underwood -- who appeared on the children's comedy show's final season in the early aughts -- was homeless. “I was not aware that she has been in New York homeless,” Bates said. “I don’t understand why no one’s talking about it.”
