True Blood will be back for a 12-episode fifth season, HBO announced Thursday.

Based on the Sookie Stackhouse novels by Charlaine Harris, the Emmy-nominated show follows part-faerie waitress Sookie, played by Anna Paquin, and 173-year-old vampire Bill Compton, played by her real-life husband Stephen Moyer.

"I remain amazed and delighted by the enthusiasm of our viewers," Ball said. "I can't imagine having more fun than this."

Season 4 of True Blood, which ends Sept. 11, is airing on Sundays at 9/8c on HBO. The current season's premiere pulled 5.1 million viewers — 38 percent more than the Season 3 debut.
