Carrie Underwood's 5-month-old son Jacob Bryan Fisher is already her biggest fan.
The singer, 36, shared a video on Saturday featuring her husband, former pro hockey player Mike Fisher, singing to Jacob and the baby's hilarious reaction to his voice.
Every time Fisher belted out Vince Gill’s 1992 hit “I Still Believe In You," Jacob bawled. But Underwood's singing voice elicited a sweeter reaction.

Fisher offered a different response for why Jacob didn't appear to enjoy his singing skills.
"The real reason is he was hungry and wanted your food. #notmysinging," he commented, adding some laughing emojis.
Justin Timberlake described the video as "the greatest thing I’ve seen all year."
