Prepare to have all hearts melted as Carrie Underwood plays with her baby boy in live action.

Carrie Underwood Looks Super Fit One Month After Giving Birth

On Monday, the country superstar added a video to her Instagram page where she sits down and holds her nine-month-old son, Isaiah, in front of her. As the mom makes cute faces at her son, she pulls him towards her and kisses his tiny lips.

What makes this video more swoon worthy is how Underwood pulls away and laughs hysterically saying that her baby is "slobbering" all over her.

But with her big smile, she tells her little boy that she doesn't mind his saliva running down her mouth. So she pulls him back in for another kiss.

Underwood then turns away again and adds more laughter giving the impression that she's on cloud nine.

In the video's caption, the singer wrote that kisses from babies are "the best thing in the world" and Isaiah makes life "better in every way!"

See the adorable moment below.

Meanwhile, Underwood previously spoke to Extra about going on tour and making sure the bus is baby proofed for her child.

"I can just picture him in the trash, 'Isaiah in the trash again,'" the boy's mother joked. "So we got magnetic locking mechanisms."

Isaiah's father is Underwood's husband, Mike Fisher.
