*After three seasons, TNT has canceled the medical drama “HawthoRNe,” the network announced today.

The series, which starred Jada Pinkett Smith as hospital executive Christina Hawthorne and Michael Vartan as her husband, surgeon Tom Wakefield, aired its final episode on Aug. 16.

TNT said in a statement it “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 actress herself broke the news earlier today on her personal WhoSay page.

“Hey everyone…if you don’t know Hawthorne will not be returning for another season,” she wrote.

“I want to say thank you to all the fans for being Hawthorne soldiers,” she added. “All our facebook fans…twitter soldiers and viewers…you held us down. Of course you know there is more to come…believe it!”

The series had generated headlines recently, with rumors that Smith and her castmate Marc Anthony, recently split from his wife Jennifer Lopez, had engaged in an affair. Smith and her husband, Will Smith, issued a statement denying the rumor.
