January Jones covered her growing bump in a flowy white top as she walked around the Century City mall in LA yesterday. She checked out a few stores and chatted on her phone during the outing, which came after an exciting weekend for the star. January Jones's Malibu baby shower was on Saturday, and her Mad Men costar Christina Hendricks was on hand for the festivities. The ladies are getting ready to start filming season five of the series next month, though creator Matthew Weiner has plans to handle the challenge of January's pregnancy. He said, "I will have to deal with her being absent for maternity leave. But we can work around her. There's going to be some new people." January will be a real-life mom long before the show airs in 2012, though we'll have to wait until then to see what happens with her character, Betty Draper.
