The country singer came out to celebrate Mike Fisher's 1,000th NHL hockey game on Monday in Nashville, Tennessee.
At the event, Underwood even planted a big ol' kiss on her handsome hubby as she held onto their adorable 12-month baby boy, Isaiah, in her arms.
It also looked like Isaiah was just as fascinated with the moment as he gazed up at his famous parents.
Fisher was honored with a large plaque of his stats for his career milestone just before his team, the Nashville Predators, faced off against the Los Angeles Kings.
"I'm so proud of you for so many reasons," Underwood said to Mike during a pre-recorded video at the game. "Specifically tonight I'm proud of you because I know how hard you work at everything you do and how much dedication you have towards hockey and towards this team. And I just think you're the best."
Carrie and Mike -- who said "I do" back in 2010 - definitely look like they're still head-over-heels for one another!
