Carrie Underwood had some good company on her tour bus this weekend: her husband, Mike Fisher, and young son, Isaiah.

The 32-year-old singer, who was performing at Washington state's Watershed Festival on Sunday, shared an adorable shot of her biggest cheerleaders before the show.

In the Instagram photo, baby Isaiah gazes outside, gently propped up by Fisher's hand.

"My boys...checking out the world through the bus window," Underwood captioned the sweet image.

This isn't the first family photo the proud mom has shared with fans.

In June, she posted a picture of Isaiah and Nashville Predators hockey center Fisher napping together.

And in March, Isaiah could be seen paying tribute to his dad by holding a Predators hockey stick.

The couple welcomed Isaiah, their first child, earlier this year. "Tiny hands and tiny feet...God has blessed us with an amazing gift! Isaiah Michael Fisher - born February 27," Underwood wrote on Twitter shortly after his birth.
