January Jones  visited her favorite LA yoga studio yesterday afternoon, just a few hours after it was announced that Mad Men earned a whopping 19 2011 Emmy Award nominations . Not only was the show recognized in the best drama series shortlist, but her costars Jon Hamm , John Slattery, Elisabeth Moss , and Christina  Hendricks are all up for individual honors. January may not have gotten a nod of her own, but the AMC hit was also recognized for best cast, a category that recognizes the series' acting as a whole. The upcoming fifth season of the drama began filming this month in LA, and creator Matthew Weiner has kept mum on how he'll shoot around January's real-life pregnancy. January announced that she was expecting her first child in late April, but has kept busy as she awaits her little one's arrival between new episodes as Betty Draper and making the promotional rounds for X-Men: First Class.
