Just like their dad, Neil Patrick Harris' adorable twins are proving they're made for the stage.
The actor and star of the new TV show "Best Time Ever" posted a video on Facebook Thursday showing 4-year-olds Harper and Gideon belting out tunes over breakfast, before heading off to preschool.
After Gideon's rendition of the "Star Wars" theme, Harper starts singing "Good Morning" (from "Singin' in the Rain") and then a jingle about how much she loves "My Little Pony." The camera then zooms back to her brother, who says, "Hi book face." Harris corrects his son's endearingly hilarious mistake: "It's Facebook."
Harris' husband, David Burtka, also makes a cameo in the viral clip, which has been viewed more than 400,000 times.
Harris sat down with TODAY.com earlier this month, explaining how his kids give him energy after a long day on set.
"They kinda fill me back up," he said. "The kids are at a wonderful age where they want to hug and sit on your lap and show you things, and make stuff together."
The twins recently started their second year of preschool.
"I'm just such a fan of them learning cool, clever things, whether it be fish in a fish tank and how they work, or letters, or building things ... it's really fun for me," Harris said. "I forget how many things they're supposed to learn."
