Jon Hamm and Jessica Pare Filming Mad Men Pictures

Jon Hamm and his small screen love interest Jessica Paré filmed a dramatic scene for Mad Men in LA yesterday. The couple seems to be fighting, despite becoming engaged in the final episode of season four last year. We'll have to wait until season five airs in 2012 to find out the real status of their relationship. Production on the Emmy-winning drama started this Summer and, in addition to Jon and Jessica, John Slattery and January Jones have also been spotted on set. January returned to work earlier this week for the first time since giving birth to Xander and she brought the little guy along to meet her cast mates. We got a glimpse of Xander's sweet face during another outing with January, though she left her son behind to run errands yesterday.
