NBC is negotiating with Donald Trump to extend “The Celebrity Apprentice” for two more seasons, we’re told. Sources tell us that the Peacock Network wants The Donald to sign on the dotted line for two more seasons ahead of the live finale of the current season on Sunday, May 20. Aubrey O’Day, Arsenio Hall and Clay Aiken are the three finalists left vying to be hired. A source told us, “Donald has so far preferred signing season by season, but now NBC wants him to commit to two more seasons.”
