Country superstar Carrie Underwood just gushed over her husband in a sweet Twitter post.

Carrie Underwood & Tour With Son Chatter

On Friday, the singer's husband, Mike Fisher, turned 35-years-old. Underwood wished him a happy birthday by telling him that he is the best husband she could ever have and the best father for their two month-old son, Isaiah.

Meanwhile, Underwood took to Instagram over the weekend to post a new photo of her baby boy along with her spouse as they take a nap on a couch. This was apparently for the baby's first band rehearsal, but he and his daddy needed a little break to rest.

The pic is captioned, "Isaiah's first band rehearsal...as you can see he & his daddy were totally into it! #naptime #earmuffs #sweetdreams."

Fisher and Isaiah show that they are indeed father and son since they nap in almost an identical position. A number of fans commented on the picture by saying how adorable they find these two to be.

One user wrote, "Way too cute!" while another added, "How sweet."

Underwood previously spoke to Win Country about her song "Little Toy Guns" where she implied that she doesn't want to be the type of parent who argues with her husband in front of her child.

"There's these characters in the song," the country icon. "And there's a little girl, and she hears her parents fighting, as unfortunately a lot of kids do, and you don't really realize how that can affect your child. And I've seen it firsthand from different people in my life."
