What Neil Patrick Harris' children really think of him
While the actor has won both an Emmy and a Tony award, his children just think of him as dad. During a recent appearance on Today with Jenna & Sheinelle, Neil got candid about what the twins think about his career.

Contrary to Sheinelle's take, Neil confessed: "Oh, I don't think they think I'm cool at all. I'm one of their fathers."
Regardless of what Harper and Gideon think of their dad, Neil is proud of his kids. "My son Gideon now, is going to a professional performing arts school, here in New York. So he wants to be an actor as well," he told Jenna Bush Hager, continuing: "They're just amazing human beings. I think the world of them."
