Kelsey Grammer Ties the Knot With Wife Kayte...Again

Boss star says an "I do" redo to his fourth better half in Las Vegas

Maybe two times the charm. 

Fifteen months after they tied the knot for the first time, Kelsey Grammer and his wife Kayte wed again Saturday night in an intimate ceremony at the Little Church of the West in Las Vegas, according to People.

"Kayte's the most wonderful person in the world," the 57-year-old Boss star told the mag. "I'm just so happy! We're really excited."

So what prompted the "I do" redo? 

"We wanted to celebrate and re-dedicate [ourselves] to how much we love each other, and to our growing family around the bend," Grammer went on. "I love that she had the courage to marry me twice!"

The couple, who wed on February 25, 2011 are expecting twins this summer.
