Fisher, who plays in the NHL for the Nashville Predators, wished his wife a Happy Birthday on Tuesday afternoon, insisting that she's got to be an "early favorite" for mom of the year.

Why Carrie Underwood Might Make Millions From Son's Baby Photos 

The Little Toy Guns singer's birthday this year came just weeks after her son's birth. Isaiah Michael Fisher was born on Feb. 27, though the country star and her NHL husband waited until March 3. to announce the big news on Twitter.

So far the Twitter pic is the only photo the couple has released to the public. It's possible they could sell his official reveal to a magazine for a big pay day, or they could elect to share the images themselves.

Underwood is currently preparing for her upcoming tour, which will take place this summer. She plans on bringing little Isaiah along for the ride and has already prepped her tour bus to accommodate the baby. The country star will also forgo solo shows in favor of festivals, which will allow her more time with her little guy.

For now, Underwood and Fisher are spending some quality time at home in Nashville with their baby boy.
