Kelsey Grammer and Kayte Walsh are expecting twins.

The 'Fraiser' actor and the former flight attendant - who tied the knot in February 2011 - cannot wait for the new arrivals, and he revealed Kayte is in her second trimester.

Kelsey - who already has four kids, Spencer, 28, and Greer, 19, from previous relationships and 10-year-old Mason and Jude, seven, with ex-wife Camille Donatacci - explained: "I'm really looking forward to meeting these new arrivals in our lives."

Speaking about his wife at the Golden Globe Awards last night (15.01.12), he added: "She's one of the most loving, amazing, warm human beings I've ever met."

Kelsey and Kayte suffered heartache when she suffered a miscarriage in October 2010, but the actor revealed last year that he wanted to have more kids because he never "tires" of being with his children.

He explained: "I'd like more kids. I never tire of them. My eldest daughter, Spencer, is expecting my first grandchild.

"Hopefully, my younger children will be able to live with me and Kayte soon. I'm working on it."
