TNT has decided not to order a fourth season of HawthoRNe. TNT truly appreciates the tremendous dedication of everyone involved in HawthoRNe. The series gave TNT the opportunity to work with many outstanding people, including Jada Pinkett Smith and the rest of the show’s talented cast, crew, producers and writers. We wish everyone involved with HawthoRNe nothing but the best.
