Back in January, Carrie Underwood and her husband, Mike Fisher, welcomed their new son, Jacob Bryan Fisher, and today (March 22) they're celebrating another milestone as Fisher officially becomes an American citizen.

The former NHL player, who was born in Ontario, Canada, posted a photo of himself in a courthouse waving an American flag to his Instagram Stories. "Big day I'm officially American," he wrote.

Fisher, 38, and Underwood, 36, have been married since 2010.
