The Country superstar took to social media to show off the epic cake presented at her son’s recent birthday party which centered around one of his favorite hobbies — Taekwondo.

"Today we got to celebrate our sweet Isaiah turning 9!!!!" Underwood captioned the post that featured a two-tiered martial arts cake, beautifully decorated with Taekwondo belts, the ATA logo, Isaiah’s name and a high-kicking topper. "Oh, how time flies..."

According to her caption, Isaiah spent his party introducing some of his best pals to the sport of Taekwondo at a Nashville-area studio. “We got to party doing one of his favorite things…taekwondo! So fun to see the kids learning some new things. And what an amazing cake from @iveycakestore !!! It was as yummy as it was cool!”

No surprise that little Isaiah enjoys his own dose of physical challenges as his dad — former pro-hockey player, Mike Fisher and mom both prioritize physical health in their every day lives. Underwood formerly shared with Audacy’s Katie Neal that her kids are a big inspiration for her to stay fit and she hopes the inspiration will go both ways as they get older.

“I’m trying to be a good example for them as well,” Underwood told Katie Neal. “I really want them to be like, ‘Man, my mom was crushin’ it. Like, up until when she was in her 90s she was still working out and gardening and could haul stuff around…. My mom just kicked some booty, even as a little old lady.’”
