Underwood and Fisher first met in 2008 through Fisher's friend, who knew her bass player. He drove to Toronto to meet her, and she had him join the meet-and-greet line so it wouldn’t be awkward if the meeting didn’t go well.
The two started dating shortly afterward, and he proposed to the ‘Before He Cheats’ hitmaker in December 2009.
A month later, Underwood and Fisher made their first public appearance as a couple at the Bell Sens Soiree at the Hilton Lac-Leamy in Gatineau, Canada.
Fisher and Underwood tied the knot on July 10, 2010, in Greensboro, Georgia.
After four years of marriage, she announced her first pregnancy in September 2014 before performing at the 2014 American Country Countdown Awards in Nashville.
And on February 27, 2015, the pair welcomed their first child, son Isaiah Michael Fisher.
