Jamaica Plain actress Julia Jones was with “How I Met Your Mother” actor Josh Radnor — a.k.a. Ted Mosby — at the Maui Film Festival on Wednesday. The photographer who took this photo of the twosome labels Jones as Radnor’s “girlfriend” in the caption. We haven’t confirmed that detail with Jones, but they sure make a cute couple. Jones was also with Radnor at a screening of the Emily Blunt movie “Your Sister’s Sister” just a few days before Maui. Jones is best known for playing female werewolf Leah in the “Twilight” franchise. She’s a graduate of Boston Latin. Radnor is in Maui to promote his latest directorial project, “Liberal Arts.” He costars in the film with one of Jones’s “Twilight” friends, Elizabeth Reaser — a.k.a. Esme Cullen.
