Ashton Kutcher Finally Shares Details from His "Ninja" Wedding to Mila Kunis

While the couple tied the knot back in July, the actor finally admitted that they got hitched in a top secret wedding.

"That was sneaky," Ellen DeGeneres says on today's show. "You got married, and every time you've been here or Mila's been here, you've been really cagey about the whole thing. And then you went and got married without any of us being invited!"

It turns out, the "That '70s Show" stars were nervous about helicopters trying to take pictures during the ceremony.

"It's a legitimate concern," he says. "I was, like, posting things on social media that were in different locations to avoid that, because we didn't want to be screaming our vows at each other and be like, 'Forever! 'Did you say never?' We didn't want to do that thing, so we went really under the radar with it."

Kutcher also talks about his 17-month-old daughter, Wyatt. "She loves dancing. She's down with dancing. I mean, if I sing 'The Wheels on the Bus Go Round and Round,' she loses it. That's her thing. She just loves it when the wheels go round. We go to the playground and she gets on the little steering wheel on the playground thing, and the wheels go round. She gets excited," he explains. "She likes to 'Whip and Nae Nae,' too. I think she thinks she's doing it, because it's whippin' and whippin' and nae-nae-ing. Mama taught her that."

While fans don't get to see a new pic of the little one, Ashton did confirm this mysterious pic from November was, in fact, a shot of his daughter.

"She's got a full thing of hair going on," he says. Now that she's a little older, "She's actually crossed that threshold. That first year, you spend just trying to keep them alive. And then after that, you actually hit a point where your job is to keep them from killing themselves...She tries to kill herself on a regular basis. Like, she doesn't realize that's a cliff and that could be dangerous. She'll just jump off the thing. She don't know yet. You'd think that they would come with instincts around fire and large falls, and they don't. I don't understand how prehistoric man lived. How did they in the jungle not jump off waterfalls and just know?"
