January Jones & Jason Sudeikis Split

Mad Men‘s January Jones and Saturday Night Live actor Jason Sudeikis have called it quits.

The couple has “been on and off for a few months and then the long distance kind of ended it,” a source told People. “But they could get back together. It was just hard to stay together with the distance.”

Mad Men tapes in Los Angeles, while SNL is filmed in New York.
