Shacked Up (2002)

Regina's man is locked up and Miles gets dumped. They figure that they have nothing else to lose, so they become roomies, and soon much, much more. Too bad no one told their ex-lovers about the change of plans. Now Regina's ex is out of jail and ready to hook back up, and Miles' old flame is moving back to town with the same idea in mind. Miles and Regina decide they will do anything to get rid of their pasts... for good.
