Neil Patrick Harris has the cutest family ever.

The actor shared a photo of him, his partner David Burtka and the couple's two kids, Harper and Gideon, posing in their Halloween costumes -- and they're one adorable group.

While the two dads dressed as Tweedle Dee and Tweedle Dum, the kids were all done up as Alice and the White Rabbit from "Alice in Wonderland."

"Our costumes for the Halloween carnival at the kids' preschool yesterday," Harris wrote about their costumes. "But 10/31 will be frighteningly different..! @DavidBurtka came up with both themes/costumes. He's amazing."

We can't wait to see what they dress up as on the 31st!
