Mrs. Draper has some secrets of her own.
The “Mad Men” mom announced Thursday that she’s expecting her first little one in real life, though she didn’t reveal the father.
"January Jones is happy to announce that she is expecting her first child this fall," her rep told People.
The 33-year-old actress, who plays housewife Betty Draper on AMC’s hit drama, is “really looking forward” to her next role as a single mom, a source close to Jones told People.
Jones and her last known flame, "SNL" funnyman Jason Sudeikis, broke up in January, according to the "Today" show's Scoop blog.
She’s next set to appear in “X-Men: First Class.”
