January Jones: New 'Mad Men' Episode Sunday!

January Jones cradles her adorable son Xander as the two leave their hotel on Tuesday (May 8) in New York City.

The 34-year-old Mad Men actress tried to keep a low profile as she headed into the city.

January attended the 2012 Met Ball earlier in the week. At the Boom Boom Room After Party, she shared a private booth at the top of the Standard Hotel with Jason Wu, Ian Somerhalder, Nina Dobrev, and Diane Kruger.

An all-new episode of Mad Men airs this Sunday! This week’s episode is called “Dark Shadows.” You can catch Mad Men Sundays at 10/9c on AMC.

Also pictured inside: January stopping to fill up her car at a gas station Wednesday (May 9) in Los Feliz, Calif.

FYI: January is using her Ergo baby carrier.
