Wait Until You Hear the Theme of Carrie Underwood’s Son’s First Birthday Party

Over the weekend, Carrie Underwood's son Isaiah turned one!

America's sweetheart Carrie Underwood has a successful career, handsome hubby, and now, a sweet one-year-old son!

Carrie Underwood and her husband Mike Fisher welcomed a beautiful baby boy to the world on February 27th, 2015. In the weeks leading up to baby Isaiah's first birthday, the couple had no idea what his birthday theme should be.

Underwood shared with Entertainment Tonight:

People are like, 'What is he in to?' I'm like, 'I don't know, he's one!'

Finally, they decided on a punny theme based on their last name, Fisher... that's right, a fish-themed party!

Is that not the cutest thing you've ever seen?!

Happy Birthday Isaiah!
