Ashton Kutcher appears on The Ellen DeGeneres Show today, and we never thought we'd see the day where the former Punk'd star talked about being a doting daddy!

"[T]he most amazing thing about having a baby is my partner, Mila," he gushed. "She’s the greatest mom I can’t even, like I go to work every day and I come home and she’s like perfect. And it just seems like everything went amazing. And I know that something probably didn’t go amazing, but she never tells … it’s unbelievable. She’s incredible." Awww!

Ashton reveals that he and fianee Mila Kunis don't have any nannies, and that co-parenting with her is "awesome" and "unbelievable."

"It’s just how much you can love another person," he continued. "You think you know how much you can love another person and then you have a child and you realize you didn’t know. It’s infinitely rewarding. There’s a great quote by Carlos Slim and he said 'most people think they need to make a better world for their children, but the reality is we need to make better children for our world.' And I try to live by that. And I think I really look at this as the greatest opportunity of my life."

On a different note, Ashton hints that Charlie Sheen will be joining the finale of Two and A Half Men in February. What?! Click thru to see that part of the interview...
