PHOTO: New Mom January Jones Steps Out with Baby Xander

The Mad Men star takes her son out in public for the first time since giving birth on Sept. 13 -- but she's still not saying who the dad is

January Jones had a big date on Tuesday: taking her 2-week-old son Xander Dane to a friend's house! It's the first time that Jones, 33, has been seen out and about with her new baby.

The single mama, who remained lean throughout her pregnancy, was looking svelte in a sheer top and black pants. It remains to be seen whether her pregnancy will be worked into Mad Men's fifth season, which started shooting in August -- but she could certainly squeeze back into those wasp-waisted '60s fashions now!

Speaking of Mad Men, Jones' colleagues on the show all seem thrilled to welcome Xander to the family. Costar John Slattery tells People that the child is "beautiful," and that January is "in love with that boy," while Elizabeth Moss has said that she "can't wait to meet" Xander. And show creator Matthew Weiner gleefully reported that Xander was the winning show's good-luck charm at the Emmys: "Her baby had his fingers crossed," he told reporters backstage at the ceremony. "(January) told me that."

The identity of Xander's father is still a mystery -- and probably will remain so. After the birth on Sept. 13, Jones left the birth certificate blank. We can't even make guesses based on what he looks like, since Jones was careful to hide the little guy's face on Tuesday! Given his mother's genes, though, we've no doubt he's gorgeous -- whoever the dad may be.
