January Jones and Xander in NYC Pictures

January Jones took a morning stroll in Manhattan today with her son Xander. The duo have been calling NYC home for the past two weeks as she makes the promotional rounds for Mad Men's fifth season. January was absent from the show's two-hour premiere, but she'll be back on soon reprising her role as the former Mrs. Don Draper. Don's new wife Megan, played by Jessica Paré, generated a lot of buzz following Sunday night's debut — what did you think of Megan Paré's Zou Bisou Bisou rendition?

January was back in the spotlight at the NYC premiere of Jules Massenet's "Manon" at the Metropolitan Opera last night. January wore a sexy, backless YSL gown and Cartier jewels to join Amber Heard, Emily Rossum, Chloë Moretz, and Emma Roberts at the formal soirée.
