Kelsey Grammer and Kayte Walsh Tie The Knot!

Kelsey Grammer and Kayte Walsh make it official!

The 55-year-old actor and his 29-year-old British flight attendant exchanged vows during an afternoon ceremony at the Longacre Theater on Broadway in New York City on Friday (February 25).

The nuptials were followed by a super-luxe reception held that night at the Plaza Hotel's Grand Ballroom.

The bridesmaids and groomsmen included some of Grammer's kids from previous relationships: his grown daughters Greer Grammer, actress Spencer Grammer and his 5-year-old son with Camille, Jude. (Kelsey and Camille's daughter Mason, 8 was a no-show.) Walsh's sister, two brothers and nephew rounded out the bridal party. (Their pals Angela Copeland and Carl Degersdorff served as Maid of Honor and Best Man)

Earlier this month, Kelsey expedited his divorce from Camille Grammer in order to wed Kayte.
