Until the January premiere arrives, Downton Abbey fans can enjoy a new trailer for season 3 of the popular PBS show.

With a children's chorus singing Lou Reed's "Perfect Day," the teaser opens with new cast member, Shirley MacLaine, playing Lady Cora's American mother, Martha Levinson.

"Come war and peace, Downton still stands and the Crawleys are still in it," MacLaine says stepping out of a car in the beginning of the new trailer.

"She finds our underbelly every time," Dowager Countess (Maggie Smith) says.

"No family is ever what it seems from the outside." The new trailer also teases a ruined wedding, steamy makeout session and, as always, stunning costumes.

The third season of Downton Abbey will premiere in the U.K. on Sept. 16. Watch the trailer above and tell Us: Which storyline are you most excited to watch?
