In the clip, Jacob is lying on the bed while dad Mike Fisher is leaning over him. Fisher begins poorly crooning Underwood's song "Love Wins," making little Jacob cry.
Underwood interrupts her husband with her signature powerhouse voice. His reaction is a world's difference.
"Everyone's a critic," Underwood captioned the sweet video.
As Jacob continues to wail when Fisher attempts to hit Underwood's notes, Underwood can be heard giggling in the background.
