Kelsey Grammer says his family are "ecstatic" about his new baby boy.
The 70-year-old actor welcomed son Christopher into the world in October, and he says his loved ones - including children Faith, 12, Gabriel, 10, and eight-year-old James with wife Kayte Walsh, as well as Spencer, 41, Greer, 33, Mason, 23, and Jude, 20, from previously relationships - are happy with their famous dad's new arrival.
"The family's ecstatic. We're all really having a great time. It's really lovely," he told People magazine.
The Frasier star said it had been "awesome and fantastic" becoming a dad again, and he's still on great terms with the rest of his family.
"We are closer than we've ever been as a family, and I'm proud of that."
Grammer announced in late October that he and his fourth wife Kayte has welcomed their new son into the world.
"Just had our fourth one, so it just became eight kids!" he told Pod Meets World.
"It was like three days ago. Christopher just joined the family."
The Frasier star - who acted with daughter Kandace on the sitcom's revival and with so Spencer in TV film The 12 Days of Christmas Eve - loves getting to spend time with his kids, particularly having them all "in the same room together".
He previously told Variety: "My work has allowed me to do that.
"I've been given this great experience. It's been painful and challenging and hard and tragic - all those things. But boy, it's a great life. And I want to pass that on to them."
