TNT orders sixth season of 'Rizzoli and Isles'

Even before season five returns to the airwaves from its mid-season finale, TNT announced that it has ordered season six of Rizzoli & Isles.

TNT has ordered 18 episodes for season six, which is expected to premiere in summer 2015. Starring Angie Harmon and Sasha Alexander as the titular mismatched murder-solving duo, the show has down well in the ratings, becoming the No. 1 basic cable show this past summer with 7.6 million average viewers in Live + 7. The crime procedural has consistently done well since the series began in 2010, ranking as one of the top five basic cable shows for five consecutive years.

Rizzoli & Isles is set to return for season five on Feb. 17.
