Kelsey Grammer is keen to expand his family a week after becoming a dad for the sixth time.

The new grandfather's young wife, Kayte, gave birth to the couple's second child, Gabriel, on 22 July (14), and the proud dad is already gunning for more kids.

The former Frasier star, 69, tells Closer magazine, "I may want to have a bigger family. We talk about it. I love being a dad and I have for some time now. This is just the next chapter of that part of my life, and I'm ecstatic about it.

"The great thing about my life is I'm always prepared for surprises. I would never anticipate what it's going to be like - easy, difficult or otherwise. I just take it in stride. We're prepared! We're just happy about our new arrival."

Kelsey's eldest daughter, 30-year-old actress Spencer Grammer, gave the actor his first grandchild two years ago, when she welcomed son Emmett.

Grammer adds, "He's a terrific kid. He was over the other day. My daughter Faith - his aunt - and my grandson were swimming together. They get along really well. So that's been fun."
