Olivia Munn is being called the New York Rangers’ good luck charm after the team’s win over the Islanders on Monday night secured them the top spot in the NHL’s Eastern Conference. Munn, who has been linked to Ranger Brad Richards since November, was spotted in the stands at the Garden that night. “Fans in the crowd kept high-fiving her after the win, and thanking her,” a spy tells us. Following the game, Munn was spotted in the Meatpacking District celebrating the Rangers’ victory with friends over dinner. We’re told Richards was not along for the ride. But he and Munn spent quality time together on Christmas Eve — spies at hip TriBeCa boite Smith & Mills spotted the low-key pair cuddled up together at a table while on a double date. Munn and Richards were “laughing a lot and very affectionate,” said a source, adding, “Brad was very attentive to Olivia, helping put on her coat and holding her hand as they left.” Munn’s starring in Aaron Sorkin’s upcoming HBO show, “The Newsroom.”
