Rachel McAdams knows how to make a scene! The actress (and hockey enthusiast) was out of her seat and made it onto the JumboTron while watching game 4 of the NHL Stanley Cup Finals at TD Garden in Boston. There with her family and friends, including her father and sister, McAdams was captured so many times on the screen cheering wildly as the Boston Bruins defeated the Vancouver Canucks. According to a source, the actress is a major Bobby Orr fan, and when they showed him on the screen, she and her whole family went crazy. McAdams was also all decked out in Bruins gear and kept popping up on the the JumboTron, jumping and screaming as she watched the game.
