Carrie Underwood pleased fans by sharing a rare video of her son, Isaiah

Carrie Underwood's 3-year-old son, Isaiah Fisher, warmed fans' hearts when he welcomed Country Music Association festgoers to Nashville.

Underwood shared the adorable clip on her Instagram account, and Isaiah can be heard saying "Welcome to Nashville" while giving a high-five to passersby.

In the caption, she asked if any of her fans had spotted the young sprout on the bridge. 'Isaiah wanted all the CMA fest goers to feel welcome in our great city!'

She added the hashtags 'sweet boy' and 'Welcome To Nashville.' The video clips received more than 230,000 likes and 3,200 comments in the short time it's been online.

Instagram user and NYU grad student, Cheyanne Hughes, said the video clip 'is so cute,' while a user known only as Dtwondeb added that he is 'getting so big.'

Wingrider1957 shared his thoughts about hospitality and kindness, saying that 'people today could learn a thing or two from this young fella.'

Lisa Serra concurred and added that time goes by way too fast. She urged Underwood to 'enjoy every second' while he is still young.

Joanne Fite, a mother-of-four, was on her way to the festival and hoped that Isaiah would still be on the bridge by the time she arrives in Nashville.

The Country Music Association Fest is scheduled from June 7th until June 10th at the Nissan Stadium in Nashville, Tennessee.

Country music fans in attendance will be treated to a superb lineup, including Underwood, Jason Aldean, Blake Shelton and Brett Eldredge, to name a few.

Fans who can't make it to the fest can look forward to Underwood's upcoming album, Cry Pretty. In a recent interview with iHeartRadio, she assured fans she's just adding the 'finishing touches.'

Underwood also received two nominations at the Country Music Awards. Please follow our Twitter account, AmoMama USA, for more details.
