January Jones had her yoga mat in hand as she headed into a fitness class in LA today. She's back on the West Coast following a trip to NYC to promote X-Men: First Class. The pregnant actress chatted about preparing her house for the arrival of her first child now that she told us she's in a "nesting phase" and also touched on how much she enjoyed her break between projects during the press junket. January returned to sunny California just in time to celebrate Memorial Day weekend near the beach with other celebrities at Joel Silver's Malibu bash. She wasn't the only one expecting at the event, since Guy Ritchie's girlfriend, Jacqui Ainsley, was also sporting a bump during the festivities. January might have more celebrating to do if her prequel finds success at the box office this weekend after being named one of this Summer's most anticipated action films.
