Meanwhile, Ashton couldn't be more in awe of his wife.
“She’s the greatest mum,” the 38-year-old recently gushed.
“I go to work every day, and I come home and she’s 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.”
Mila, 32, and Ashton, 38, first met back in 1998 during their time on the beloved sitcom, That '70s Show.
The duo stayed friends before becoming one of Hollywood's hottest items in 2012.
During a press junket for her new film, Bad Moms, the mum candidly spoke to Entertainment Tonight about what it was like being a parent to her and Ashton's 19-month-old daughter.
"I reprioritised my life, in all honesty. I traveled through all my twenties and I was very selfish… in a good way, not in a way I regret. And I think having a kid made me realise how incredibly selfless I want to be."
"It does change the way you think and look at life. I would never trade it for the world," the Forgetting Sarah Marshall actress continued.
"But I know that when we decided to have a kid, we were ready to no longer be selfish. Or at least start the process, because innately, as humans, we are really selfish people."
