January Jones welcomes a baby boy

January Jones is a mommy! The Mad Men welcomed her first child on Tuesday, People magazine reports.

Xander Dane Jones and the new mom are “doing great,” her rep said.

Jones, 33, chose to keep the sex of her baby under wraps, remarking “it’s going to be a surprise for me” during a June interview.

The actress — who has previously dated Jason Sudeikis — announced the pregnancy in April.

“She’s really looking forward to this new chapter in her life as a single mom,” a source said at the time.
