The Matrix Reloaded actress returned to the small screen for the first time in 18 years for the show, which premiered on U.S. network TNT in 2009, but TV executives announced on Friday (02Sep11) that they will not be renewing the contract for another series.
In a statement, a network representative says, "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."
The finale of the third series, which also starred Michael Vartan and singer/actor Marc Anthony, aired in America last month (Aug11).
The cancellation news comes just weeks after tabloid reports falsely suggested Pinkett Smith had had an affair with Anthony, prompting his split from wife Jennifer Lopez.
The salsa singer has vehemently denied the claims, branding them "laughable", while Pinkett Smith and her husband, I Am Legend superstar Will Smith, have also been forced to defend their 14-year marriage amid separation rumours.
