Fans reported a sighting of Robert Downey Jr. at Cartier on Newbury Street on Saturday. We can’t confirm, but it would make sense; he’s in town with Robert Duvall to film “The Judge.” . . . Ramona Rizzo of “Mob Wives” and Jerod Mayo of the Patriots were at Strega Waterfront, separately, over the weekend. . . . The Blue Jays’ Jose Bautista spent some of his Friday night at Empire Asian Restaurant & Lounge with friends. Sox player Mike Napoli and the Blue Jays’ Adam Lind and Mark DeRosa were spotted at Red Lantern on Saturday.
