Neil Patrick Harris
and David Burkta's adorable twins, Harper and Gideon, are ready for elementary school!

The Insta-famous twins are always blowing up NPH's account and this time it's because they are preschool graduates.

On Saturday, the 42-year-old actor posted a sweet and goofy pic of the 5-year-old siblings on their first day of summer to celebrate the fact that they are heading to Kindergarten in the fall.

"Harper and Gideon graduated from the amazing Weekday School on Friday," Harrris wrote on the silly photo. "Now they're just monkeying around. #nextstopkindergarten."

Harper and Gideon were preschoolers as of last week, but that doesn’t mean they were just painting pictures and having nap time (although they probably did that as well).

The precious pair are already really hard workers who know how to earn some money, with the help of their parents of course.

On Thursday, just one day before the twins took the next step into higher education, David gushed about his children's amazing entrepreneurial skills.

"The kids made $40 selling popcorn, cookies and lemonade. Super proud of them," David wrote on yet another sweet picture of the couple's twins.

"We are sending it to the @aspca Neil [and] I said we triple the amount to help poor animals in need. They deserve a small present right?" he added.

On Sunday, the happy fathers took a break from their kids and had a parents' night out, attending the 70th Annual Tony Awards in New York.

When the duo hit the red carpet, however, Neil was NOT his usual self. The How I Met Your Mother star donned a whole new 'do and it was definitely a showstopper.

The actor revealed his dramatic new look, a completely shaved head, to the media after weeks of covering his head with a hat while out in public.

Take a peek at his new style below.
