Ashton Kutcher and Mila Kunis went on a date night without baby Wyatt as they watched a concert by Madonna at The Forum in Los Angeles.

"Mila whooped it up, lifting her hand toward the stage as the legendary musician performed," reported Daily Mail. "And Ashton flashed a smile and crossed his arms as he took in the show, which also featured an appearance from Katy Perry."

Ashton Kutcher and Mila Kunis tied the knot during the Fourth of July weekend and spent their honeymoon going on a road trip across the US, including a visit to the Yosemite National Park with baby Wyatt tagging along.

The "Jupiter Ascending" actress credited the "Jobs" actor for being very active in the life of baby Wyatt.

"My husband is an incredibly hands-on dad. When my child was born, I was breast-feeding and he said, 'That's your connection, I want to change every diaper,'" she said.

"When we're in public, if it's a pee-pee diaper you can change her at the table, but if it's a poo-poo diaper you don't want to affect the people eating. So he's like, 'Err, I guess I'm going to the ladies' room to do it,'" she added.

Mila Kunis also said during a guesting on James Corden's show that she and Ashton Kutcher make it a point to go out on dates without baby Wyatt so they could connect as partners. Their parents, who live just down the street from them, are only too willing to watch the baby on date nights.

"We make an effort to not talk about the baby. It's hard. You catch yourself though... but it's important... For that one hour, we try very hard to connect," she said.

The couple met on the set of "That '70s Show" but they didn't really have a romantic connection even if the "Jupiter Ascending" actress admitted that she had a huge crush on Demi Moore's ex.

Ashton Kutcher and Mila Kunis started dating in 2012 and they got engaged two years later. Baby Wyatt Isabelle was born in October last year.
