Kayte Walsh and Kelsey Grammer. 

Kelsey Grammer has a lot to celebrate tonight. The 56-year-old "Boss" star and winner of the best actor in a TV drama Golden Globe revealed backstage that he and his new wife, Kayte Walsh, are expecting twins. They'll be her first children and his fourth and fifth.

"I'm really looking forward to meeting them," he said. "Fatherhood is always different based upon the character who drops into your life."

He praised his wife, saying she'll make an "extraordinary" mom: "She's funny and serious, scary and humorous, all at the same time."

So will the new additions affect how he approaches the incredibly dark politico he plays on "Boss?" "I'll just be more tired actually," he said, laughing. "It wouldn't change the way I work. It just might change the amount of time I have."
