Less than three weeks after his divorce from wife no. 3 was finalized, Kelsey Grammer tied the knot with wife no. 4, the New York Post reports. Grammer, 56, and Kayte Walsh, 29, married yesterday on the set of La Cage Aux Folles on Broadway, where Grammer just finished a run in the musical. Another star of the musical performed the ceremony, and the small guest list included chorus boys, Walsh’s flight attendant friends, and Grammer’s 5-year-old son (but not his 9-year-old daughter).
