“Kelsey is thrilled to finally have time to fully enjoy being a father all over again,” a source told the publication.

“He’s been incredibly supportive of Kayte throughout this pregnancy which, though unexpected, has reignited a spark in their marriage that they both needed.

“This will be their fourth child together and, with Kelsey’s other three children from his past marriages, their new bundle of joy will have so much love.

“After giving Frasier one last go, he has hung his hat up on that character and is ready for the next phase of his life. He is looking forward to embracing the hands-on parenting he missed in the past.”

Grammer and Walsh are already parents to daughter Faith Grammer, 12, and sons Kelsey Gabriel Grammer, 10, and Auden “James” Ellis Grammer, 8.

The actor, who has been married four times, also has a daughter, Spencer Grammer, 41, with ex-wife Doreen Alderman, and daughter Greer Grammer, 33, with ex-girlfriend Barrie Buckner.

He also daughter Mason Olivia Grammer, 23, and son Jude Gordon Grammer, 20, with former Real Housewives star Camille Grammer.

In May, Grammer told US People magazine he was absorbed in his work in the early days of fatherhood.

“I have neglected a couple of the kids in my life, especially the first two. I’m trying to make up for a little of it now. I’m still their dad, so you can always have (a) chance to show up,” he said.

“I probably should have been a little more clear and maybe less tolerant with the older ones.

“I’m pretty tolerant with the young ones, but I’m clear about how there’s certain expectations and certain ways to navigate through a social situation: keep it close to the vest and play it straight, and you’re going to be well-served in your life.”
