“I would love to have another baby, but we’ll see,” she said. We’re not in any crazy rush, but I hope so. I love being a mom, I really do.’

Foster also has six adult daughters from previous relationships: Allison, 52, Amy, 49, Sara, 41, Erin, 40, and Jordan, 36.

Katharine previously insisted that the beloved couple “doesn’t care” about their age difference.

The brunette beauty shared: ‘Of course, some people think it’s a thing, but we don’t care. This is what happens with social networks [and] the people who make comments… You have to remind yourself that they make that comment and five seconds later, they’re not thinking about you anymore.’

This comes after David Foster said that he is still adjusting to the challenge of raising a young child at his age.

The veteran musician admits it’s a “different” kind of challenge than he’s used to.

David shared: “I had all the daughters up until my son and I love all my daughters immensely, but having a son is a little different.”

The musician has also approached the situation with a different mindset.

The Grammy-winning star, who married Katherine in 2019, told PEOPLE: “At this point in my life, it’s different again.” Not better not worse, just different. I’m still working, I’m still gone a lot, but maybe time is a bit more valuable to me because now I have more track behind me than in front of me.

David is also determined to pass on his ‘wisdom’ to his son.

He said: ‘I think I can offer Rennie one thing even though I won’t be around when she’s 50 or 40, or maybe 30. I think I can offer her the wisdom of my 72 years on the planet. And maybe that’s not a bad trade-off. I hope so.’
