Carrie Underwood is having some Halloween fun with her son!

On Friday, the Grammy Award winner shared a hilarious clip via Instagram Story of her son Isaiah, 7, dressed in an old man Halloween costume while showing off some funny moves during their outing to celebrate the spooky season.

"I need an old man dance, give me an old man dance," the singer said in the video before her son started to perform his imitation of the routine.

"This kid!!!!" she also wrote in the caption.

In addition to Isaiah, Underwood, 39, is also a mother to her second child, Jacob, 3. The singer shares both of her sons with her husband, a retired hockey pro Mike Fisher.

Last week, the American Idol alum also posted a cute video on Instagram of her sons in the audience of her first show on her Denim & Rhinestones Tour.

In the video, both kids sat on their dad's lap as Isaiah waved and blew kisses to mom and Jacob slept in Fisher's arms. Underwood serenaded the crowd while suspended above on a swing as her sons cheered, "Mommy!"
