January Jones chatted with a friend and walked her dog yesterday during a casual stroll near her LA home. She chose a black sheer shirt, which gave a prime view of her growing baby bump. The actress isn't expected to get back to work on Mad Men in the foreseeable future, but she's been busy promoting another project, X-Men: First Class. January talked to Allure magazine recently about her big-screen endeavor, though she didn't open up about her surprise pregnancy. She may have to trade her LA sunshine in the coming days, as she's expected to join her costars, James McAvoy, Kevin Bacon, and Michael Fassbender, in NYC this Wednesday for their press junket.
