January Jones Goes Bold in Black at the Emmys

January Jones wore a black Zac Posed gown to hit the red carpet at the Emmy Awards.

January Jones made a dramatic entrance in Zac Posen at the Emmys in LA this evening. She's back at the award show after skipping last year due to the birth of her first child, Xander, just a few days before the big event. January shared on the red carpet tonight that she recently celebrated Xander's first birthday with a car-themed BBQ party. January and her Mad Men cast are once again up for outstanding drama series, which they've won four years in a row.
