Carrie Underwood's husband shares a rare photo of their son, Isaiah, 3

The singer’s husband and famous NFL star recently shared a rare photo of their 3-year-old son.

Inquisitr revealed that Mike Fisher, the husband of Carrie Underwood, posted a snapshot of himself together with his son, Isaiah on his Instagram.

The photo showed the father and son bonding during a fishing trip on the NHL player’s day-off, according to Sounds Like Nashville.

On the caption, Fisher shared that his son had caught his first fish during their one-day vacation. Fisher gushed that it was little Isaiah who reeled the fish in.

Fisher was seen hugging his little boy as they were both all smiles in the photo while holding the fish Isaiah had caught.

Isaiah recently celebrated his third birthday on February 27, 2018.

The couple did not share any photos of their son on his special day but Underwood reportedly posted a photo of Isaiah’s cake, as revealed by Pop Culture.

His birthday party was themed and based on the Disney series, Mickey Mouse’s Clubhouse.

On Twitter, Underwood went on to thank her fans for their birthday wishes and sweet messages for her son.

Her followers also shared sweet photos of the Fisher family to mark the special occasion and wrote warm greetings for the little tot.

Inquisitr suggested that Underwood and Fisher often refrain from showing their son’s face on social media. They occasionally post photos and videos with him in it, but they are usually just snippets of him with his face away from the lenses.

In 2017, Underwood opened up about her family and their lifestyle in Tennessee, where they currently reside.

Underwood happily shared that her little boy is very “sweet.”

At the time, she said, “Our son is absolutely amazing. He’s just such a sweet guy and, you know, we have a wonderful little family.”
