Call them ladies of the Senate – Ottawa Senators, that is. Hilary Duff and Carrie Underwood were spotted in Canada Wednesday night, rooting for their hockey player boyfriends, Mike Comrie and Mike Fisher, respectively.

Underwood, 25, was seated behind Duff, 21, at the Scotiabank Place as their beaus' team, the Ottawa Senators, beat the Tampa Bay Lightning. Fisher scored the winning goal and reportedly said after the game when asked about Underwood, "Yeah, maybe it was a birthday gift for her, I guess."

Duff and Underwood have become fixtures at their boyfriends' games: "I'm the crazy lady sitting in the crowd screaming my head off," Duff said recently. Underwood first publicly cheered on her boyfriend last month.
