Mad for Xander!

Less than a month after giving birth, new mom January Jones got back to work on the Los Angeles set of Mad Men on Tuesday.

Another first? For the first time, stepping out of an office building nearby, the 33-year-old star gave the world a good glimpse of her baby son Xander Dane Jones, born Sept. 13.

Wearing shades and a lacy top, the actress held her little boy (adorable in patterned PJs and clutching his mom) close. See more pics of January and Xander from PopSugar.

Jones hasn't yet identified Xander's dad.

"He's beautiful," her Mad Men costar John Slattery told Us a few weeks ago. "She's in love with that boy."

At the Emmys, Mad Men costume designer Janie Bryant added that Jones seemed "wonderfully happy" in her first days as mom. "She is a loving, wonderful, hilarious girl who is an amazing wit and character. I think she's one of the best!"

Personally, I think the baby looks like a mini Bobby Flay, I wouldn't doubt he's the father.

Maybe she used a donor. Why does it matter who the father is? It's no-one's business but hers and eventually her child's.

I'm not jealous at all I said he's poor because she has noted ego issues and parents are supposed to give selflessly to their children. besides in the state of california you can't put the fathers name on the birth certificate if your single and he has said he doesn't want to be named. check yourselves before you critize me

He is adorable! She may have given the baby her last name because the father chooses not to be apart of the baby's life? I would do the same thing if I was in that situation.

she gave the baby her last name cause she doesnt want anyone to know the father.........sad

@ US magazine baby Xander wasn't born September 14th he was born the 13th. yeah he's cute but poor kid has a talentless so called actress with major ego problems for a mommy
