January Jones toted her pink yoga mat to a class in LA yesterday. The Mad Men actress and her costars would usually be gearing up to start shooting new episodes ahead of their usual Summer premiere, but contract negotiations may mean fans will have to wait until 2012 to see season four. All signs point to there being more of the beloved series in our future, but unfortunately those finale cliffhangers won't be resolved just yet. January will still have a busy next few months as she starts to promote X-Men: First Class ahead of its June 3 release. Most of you think they got the look of her character Emma Frost right based on the sneak peeks, and we'll see more of January and her sexy star-studded cast together soon.
