AceShowbiz - Carrie Underwood has been one of the successful female country singers, but her son has a hilarious take on her job. One day before Valentine's Day, the "Cowboy Casanova" hitmaker shared online Isaiah's answers to his "All About My Mom" preschool project, and couldn't help but crack up at his observations.

Making use of her Instagram account, the 36-year-old singer uploaded a photo of the fill-in-the-blank questionnaire that her 4-year-old has to do for his school. Interestingly, it uncovered the fact that her little boy thinks her job is to "wash the laundry" and she is really good at "folding laundry." He also noted that she is 70 years old.

Along with the snap of the worksheet, the former "American Idol" winner wrote, "Soooo apparently I'm 70 and I'm really good at doing the laundry." She added a face-with-tears-of-joy and a shrug emoji at the end of her caption.

Carrie's hilarious post attracted amused reactions from other famous stars. Fellow country crooner Miranda Lambert simply wrote, "Bahahaha." Another singer Brandi Carlile commented, "OMG! I love kids." Meanwhile, the former "Zoey 101" star Jamie Lynn Spears reacted with two clapping-hands emojis in the comment section, whereas former Victoria's Secret Angel Lily Aldridge replied with three rolling-on-the-floor-laughing emojis.

This was not the first time Carrie shared her amusement over Isaiah's remarks. In March 2019, she turned to Twitter to share his impressive word choice. "My 4-year-old just told me that something is 'unreasonable,' " she tweeted. "Where does he get this stuff?" When a fan expressed disapproval, she clarified, "Ha ha. It wasn't an attitude thing...he just threw it into a normal conversation."

Months later, the "Before He Cheats" singer gushed over her boy when talking about Mother's Day tradition. "He's such a sweet little guy, and anytime he's outside, he'll pick me flowers and things," she said. "So, I'm like, 'You're learning. You've already got me wrapped around your finger, and then you do stuff like that, and it's even more so.' "

Isaiah is Carrie's first child with retired NHL star Mike Fisher. He was born in February 2015, and is the older brother of Jacob, whom the "Jesus, Take the Wheel" crooner gave birth to in January 2019.
