The "Cheers" and "Frasier" star married 29-year-old flight attendant Kayte Walsh on Friday at Broadway's Longacre Theatre — the same place where the actor had been headlining "La Cage aux Folles" with Douglas Hodge until earlier this month.
Stan Rosenfield, a Grammer representative, called the event "a private ceremony for family and friends." A reception followed at the Plaza Hotel.
The ceremony was held before the evening performance of "La Cage," which currently stars Jeffrey Tambor and Harvey Fierstein.
Grammer, 56, received a Tony Award nomination for his role in the show, playing the suave owner of a glitzy drag club on the French Riviera.
The actor's divorce from his third wife, "Real Housewives of Beverly Hills" star Camille Grammer, became final earlier this month. They had been married for 13 years and have two young children.
It's Walsh's first marriage.
