January Jones steps out with son Xander after being spotted with new mystery man

January Jones' little guy sure is getting big! The "Mad Men" actress was spotted carrying her happy son Xander, who turns 1 next month, in Los Angeles on Tuesday after the duo hit up a jewelry store and then stopped by cafe Le Pain Quotidien, where Jones met up with some friends for lunch.

"He's becoming more of a little person. He is quite a charmer," she told Us Weekly a few months back. "I love to make him laugh. He thinks I'm funny and that's always a nice feeling."

Enter to win a trip and tickets to the iHeartRadio Music Festival in Las Vegas!

The 34-year-old donned a black sleeveless top, flowy skirt, and sandals, and had her offspring decked out in a gray T-shirt and cute plaid shorts for their Tuesday outing. As for who Xander's dad is, well, that's a secret the 34-year-old is still keeping, but Jones has gone public with the fact she's mad about a new man: She and the mystery fellow were spotted holding hands as they strolled through Santa Monica with Xander and his nanny on Monday.

At this point, all we know about the guy is he has red hair … and Jones recently dyed her hair red. Hmmm. Either it's just a coincidence, they're playing siblings in an upcoming movie, or this couple is really in love. We'll keep you posted.
