Yesterday, it was reported that the “Mad Men” star is about to become a mother! A rep for Jones had also confirmed the news, saying that the actress “is happy to announce that she is expecting her first child this fall.”

But although this is a very joyful news, sadly, the 33-year-old is keeping the details of her pregnancy private, including the identify of her unborn baby’s father.

Jones was previously linked to “Saturday Night Live” star Jason Sudeikis, who was recently announced as the host of the upcoming MTV Movie Awards. She had also been linked to some other famous guys, including singer Josh Groban and Demi Moore’s hubby, Ashton Kutcher.

Beside busy being the wife of Don Draper on “Mad Men,” the Emmy-nominated actress will next appear in “X-Men: First Class.”
