"Mad Men" actress pregnant, father not revealed

Actress January Jones, who plays sullen housewife Betty Draper on the Emmy-award winning television drama "Mad Men," is about to become a single mother, People magazine reported Thursday.

Jones, 33, is expecting her first baby in the fall. The father's identity was not disclosed. She broke up with "Saturday Night" live actor Jason Sudeikis in January, People reported at the time.

Jones has had some practice being pregnant. Her "Mad Men" character delivered her third child during season 3 in 2009. But her real-life pregnancy means viewers might see even less of Jones when the show returns early next year. She had a low profile last season in the wake of Betty's divorce from advertising executive Don Draper, played by series star Jon Hamm.
