"Hello, Ottawa," Underwood, 27, told a cheering audience of about 10,000 at the Scotiabank Place as she came on stage for her Play On tour. "So I guess I can kind of consider this my hometown."
The Nashville resident, who became engaged to Fisher in late December, didn't waste a chance to honor her fiancé, who sat about 15 rows from the stage with some friends and his younger brother, Bud. Security guards said Fisher was traveling with an entourage of about 100, reports the Ottawa Citizen.
At the end of "Mama's Song," a picture of the happy couple flashed on the screen as the crowd again cheered wildly. "Wasn't that cute?" Underwood asked.
At one point during the concert, which was filled with elaborate effects and stage presentations, Underwood waved to Fisher from a blue pick-up truck that was suspended over the audience. And in the second half, when a fan screamed out, "I love Mike Fisher!," Underwood replied, "No, I love Mike Fisher."
But Underwood saved the best for last, coming on stage for her encore performance in a Senators jersey with Fisher's No. 12 and name on the back.
