On Friday, Harris's 5-year-old twins Harper and Gideon graduated from preschool, and on Saturday, they took to the jungle gym to celebrate. Harris posted an adorable Instagram picture of the two kids showing off their skills on the playground. Harper was swinging from two rings while wearing a cute dress with an orange top and black-and-white striped skirt. Gideon, on the other hand, hung onto another ring while sporting a blue polo and khaki shorts. Harris was clearly proud of his little ones, captioning the image, "Harper and Gideon graduated from the amazing Weekday School on Friday. Now they're just monkeying around. #nextstopkindergarten." The blonde twins definitely retained some valuable business skills from their first few years of schooling. On Friday, Harris's husband David Burtka posted a picture of the two kids on his own Instagram, showing off their lemonade, cookies, and popcorn stand—which was a hit, to say the least. According to Burtka's caption, the budding entrepreneurs made $40 off their pop-up business. And if that wasn't impressive enough, the twins selflessly donated their proceeds to the American Society for the Prevention of Cruelty to Animals.
