January Jones touched down at JFK with Xander in her arms on Saturday. Yesterday, January hit the Big Apple streets wearing a striped Splendid dress without her 7-month-old son, whom she called a "charmer" at last week's red-carpet premiere of Mad Men. She's on the East Coast to promote the series ahead of its season five premiere on March 25 — check out new Mad Men pictures to gear up for the big day. January, Jon Hamm, John Slattery, Vincent Kartheiser, Jared Harris, Kiernan Shipka, and the show's creator Matthew Weiner all stopped by the Today show this morning to chat up their AMC drama. The press will continue this week with January appearing on Late Night With Jimmy Fallon tonight and Jon following with his own interview with Jimmy on Tuesday.
