9:11 AM PT -- A source with direct knowledge tells TMZ ... Jen broke up with her boyfriend, John Miller. That said, we're told Jen and Bradley have been close friends for years -- since "Alias." They have spent time together with their significant others at dinners and other occasions.
Who knows whether this is something, but when people break up they often gravitate to people they know, and lots of times that develops into something. If you didn't know that ... it's actually a thing.
