Carrie Underwood’s son Isaiah just turned four this week and Carrie serenaded her little man in a pretty funny way.
Video posted by Carrie’s hubby Mike Fishers hows the country superstar sucking down a balloon of helium and then belting out “Happy Birthday” to her boy. And guess what? She still sounds pretty darn good.
Also in the video is the couple’s newborn Jacob, who is being held by his mommy as she sings to Isaiah.Check it out below.
