Carrie Underwood delighted fans with a cute new video of her son Isaiah over the weekend.

The 33-year-old singer and former "American Idol" champion posted a clip of the 17-month-old infant beating the summer heat by playing in a kiddie pool. The video sees Isaiah giggle as he belly flops into the water.

"Summer splashes! #bellyflop," Underwood captioned the clip on Facebook.

The star's husband, NHL star Mike Fisher, had originally uploaded the video to his Instagram.

Underwood and Fisher married in Greensboro, Ga., in 2010 and welcomed their son in February 2015.

The singer revealed Isaiah loves pools while discussing her family's frequent travels with Extra in June.

"We do as much as we can. I'm always looking up baby-friendly things to do in wherever we are," she said. "We try to get out and walk as much as possible, just to kind of get out and see things. He loves being outside."

"I want him to have childhood normalcy," the star added. "We try. I think that's the important thing. We take him down to the pools at the hotels and let him splash around because a kid would do that."

Underwood last released the album Storyteller in October and kicked off her accompanying tour in January. The singer told People in May she hopes to have more children despite her busy schedule.

"I'm not sure when because we're both kind of busy these days, but yeah, [I] definitely [want to]," she said. "And I'm like, '[Isaiah's] so good -- I could do a few more of those.'"
