Ashton Kutcher and Mila Kunis may be one of the most secretive couples in Hollywood. The couple pulled off an ultra-private wedding last summer and stopped by "The Ellen DeGeneres Show" to talk about the secret nuptials, as well as their daughter, Wyatt.

"That was sneaky," DeGeneres said to her guest. "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 was a ninja effort," Kutcher said of his wedding to his "That '70s Show" co-star. "We really didn't want helicopters at our wedding and it's a legitimate concern. I was, like, posting things on social media that were in different locations to avoid it."

Kutcher explained that the secrecy behind the entire ceremony came from the couple's worry that they would have to scream their vows at each other and wanted to keep everything under the radar. The host then commended his efforts and told him, "It's hard to do, because somehow word always leaks out, no matter how careful we all try to be."

Kutcher and Kunis tied the knot in July 2015 at The Secret Garden at Parrish Ranch in Oak Glen, Calif. The venue was very secluded and surrounded by mountains and trees.

In addition to talking about his secret wedding to Kunis, Kutcher also talked about their 1-year-old daughter, who already loves to dance and sing. Wyatt can even do the whip and the nae-nae, something her mother taught her.

"I mean, if I sing 'The Wheels on the Bus Go Round and Round,' she loses it. That's her thing," Kutcher told DeGeneres. "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."

The actor then shared an adorable picture of his daughter with DeGeneres, something he already posted to his own Instagram. "She's got a full thing of hair going on," Kutcher said of his daughter, before explaining why her first year of life was the hardest.

"That first year, you spend just trying to keep them alive," he told the host. "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."
