The Crawleys are coming back: "Downton Abbey's" season four won't hit small screens until January, but it has already locked in season five.

PBS announced its popular drama will be renewed for a fifth season. The show has become that most popular Masterpiece show on PBS, according to Yahoo News.

"We are thrilled to produce a new series of the show next year. We promise all the usual highs and lows, romance, drama and comedy played out by some of the most iconic characters on television," said Gareth Neame, executive producers of "Downton Abbey". "All the actors and makers of the show continue to be humbled by the extraordinary audience response and want to take the show from strength to strength next year."

According to The Hollywood Reporter, the fourth season, which recently ended in the U.K., averaged 11.8 million viewers, ranking as the top-rated drama there, and the series is also the most-watched drama in PBS history, with last season's finale averaging 8.2 million.

Earlier this year, more than 24 million viewers watched the third season of the series in the U.S., making it the most-watched drama in PBS history. Season four will air on PBS Jan. 5-Feb. 23, following a preview special, "Return to Downton Abbey", scheduled for Dec. 1.

"Like millions of other 'Downton' fans, I can't wait to see what's next for the Crawley family," Paula Kerger, President and CEO of PBS said. "We're proud to be the home of this extraordinarily entertaining series, and, along with our stations, we look forward to sharing season five with U.S. audiences."

The show, about an aristocratic family and their servants in the early 20th century, stars Michelle Dockery, Hugh Bonneville, Elizabeth McGovern and Jim Carter.

Dockery dished to E! News recently about what is to come for Lady Mary's love life.

"There are a few potential suitors, there's two main ones," Dockery said. "The new boys coming into the show, they're brave because I'm cursed. Mary is cursed isn't she? Because they all die."
