The Little Toy Guns singer has officially turned 32 years old and the big day comes just a few weeks after the birth of her son, Isaiah Michael Fisher.

So how does she plan to celebrate? Is a big birthday bash in order? According to Underwood, she's already given herself the "best gift ever" in the firm of "a tiny semi-bald chubby dude" also known as her son.

Little Isaiah was born on Feb. 27, though his country star mom didn't announce his arrival on Twitter until March 3. Apparently there had been some trouble coming up with a name for the little guy, though in the end the country singer seemed pleased with the official moniker.

In a few months Underwood and Isaiah will embark on their first tour together on a bus complete with all then amenities necessary for caring for an infant out on the road.

For now, Underwood is currently enjoying some private time at home in Nashville with her husband, NHL player Mike Fisher, and their little boy.
