January Jones Visits Jason Sudeikis on 'Horrible Bosses' Set -- Again!

Mad Men‘s January Jones once again visits her boyfriend, Saturday Night Live regular Jason Sudeikis, during a late night shoot of his new movie, Horrible Bosses, on Wednesday night (July 28) in Woodland Hills, Calif.

“She just comes and hangs out every day,” a source reveals. “At one point, people were joking that they should give her a part in the movie because she’s there so often.” Ha!

A few weeks ago, JustJared.com exclusively broke the new that January, 32, and Jason, 34, were an item.

Horrible Bosses is about three friends (Jason Bateman, Sudeikis, Charlie Day) who conspire to murder their awful bosses (Kevin Spacey, Jennifer Aniston, Colin Farrell) when they realize they are standing in the way of their happiness.
