Shameless” has been renewed for a seventh season.

The renewal, announced Tuesday by Showtime CEO David Nevins at the Television Critics Association press tour in Pasadena, Calif., comes just two days after the dramedy’s Season 6 premiere.

All key cast members are expected to return for Season 7, according to Nevins.

The order, like previous seasons of “Shameless,” consists of 12 episodes. Season 7 will head into production sometime this year.

“Shameless” kicked off its sixth season this past Sunday with nearly 1.5 million viewers up against the Golden Globes on NBC. Last season, the dramedy averaged about 1.6 million viewers in “live plus same-day” estimates from Nielsen, making it the network’s second most popular show behind “Homeland.”

Starring William H. Macy and Emmy Rossum, “Shameless” debuted in January 2011. The series revolves around the dysfunctional Gallagher family, headed by patriarch Frank Gallagher, played by Macy.

Also at TCA, it was announced that the fifth season of Matt LeBlanc’s “Episodes” will likely be the final season of the series.
