The 55-year-old "Cheers" and "Frasier" star said on CBS' "Late Show With David Letterman" on Thursday night that he's marrying Kayte Walsh.
He says that "Kayte's my new girl" and that they're getting married "in February, we think."
His wife of nearly 13 years, Camille Grammer, filed for divorce in July. She cited irreconcilable differences.
She stars in Bravo's "The Real Housewives of Beverly Hills." They were married in 1997 and have two young children.
