Who's the lucky father? People magazine has learned through January Jones' rep that the Mad Men bombshell is "expecting her first child this fall." Aside from announcing the big news, Jones is keeping mum on other details for now. Here's hoping the star is a better mother than her Mad Men counterpart Betty Draper. "She's really looking forward to this new chapter in her life as a single mom," said a source close to the actress. Jones, 33, is starring alongside Jennifer Lawrence and James McAvoy in the upcoming comic-book series film X-Men: First Class. But Betty Draper is on a bit of a hiatus: Season 5 of Mad Men will not air until 2012.
