"Mad Men" star January Jones has split from her funnyman boyfriend Jason Sudeikis, according to reports.
The couple became a hot Hollywood item last summer but never spoke publicly about their romance.
A source tells People.com, "They've been on and off for a few months and then the long distance kind of ended it."
Jones lives and works in Los Angeles, while Sudeikis, a "Saturday Night Live" regular, is based in New York.
