Pictures of January Jones Visiting Jason Sudeikis on the Set of Horrible Bosses

January Jones stopped by the LA set of Horrible Bosses last night to say hi to her guy Jason Sudeikis — the cast list for the Jennifer Aniston comedy keeps growing, and the Old Spice guy, Isaiah Mustafa, just nabbed a role! While Jason doesn't strike you as Hollywood's next big ladies man, it's clear that at least January is smitten with the SNL star. She's back in California and able to spend time with him after a quick trip last week to NYC, where she hit the spa and visited with Jimmy Fallon. January also met up with her Mad Men costar Elisabeth Moss to celebrate their show's new season, which features amazing period decorations and new parenting challenges.
