It looks like Nicole Kidman and Keith Urban are done having kids.

Kidman recently sat down with BBC 2 for an in-depth interview on her career and family with the country superstar. In her most recent role, Lion, the actor portrays adopted mother Sue Brierley, so naturally, the conversation segued into children.

Journalist Victoria Derbyshire asked Kidman if she would considering adopting again, as the mom of four has two adopted children from her previous marriage with Tom Cruise, as well as two daughters -- Faith Margaret and Sunday Rose -- with Urban.. While Kidman would be open to "two or three more" children, she shares that Urban is "kinda maxed out. He's like, 'I'm done baby, I'm done. Let's just focus on what we have.'"

"That's the balance of a relationship, isn't it?" Kidman asks. "I would never go against what he wanted in terms of our family. He's right in a way. There's only a certain amount of time and you want to be able to give the time to each person."

Kidman further explains why she loves children so much.

"I love raising children," she gushes. "They make me feel good and I love being around and I love the ups and downs, and I love watching them grow and the things they say and teach."

Urban and Kidman celebrated their 10th wedding anniversary in 2016. When asked about the key to having a successful marriage, Kidman admits that she has no key. She adds that the biggest thing you can have in a relationship is humility.

"I think everyone's relationship is their own. What goes on behind closed doors and what you are is what you are," she reasons. "I'm lucky that I met somebody that I love and I like."
