Kelsey Grammer took pregnant girlfriend of two months Kayte Walsh to the premiere party of The Romantics in NYC on Tuesday night.

Grammer, 55, and British flight attendant Walsh, 29, have been dating for about two months. A rep for the Frasier actor confirmed the news last month to after Walsh's dad spilled the beans to the UK's Daily Mail.

The Emmy winner filed for divorce from his third wife, former Playboy model Camille Dontacci (who'll star in the upcoming Real Housewives of Beverly Hills) in July after 13 years of marriage. The former couple has two kids: daughter Mason, 8, and son Jude, 5. Grammer also has a 26 year-old daughter, Spencer, from his first marriage -- and another child, Greer, 18, born out of wedlock.

Of Grammer's latest romance, Kayte's father Alan Walsh told the Daily Mail, "I think they met in New York socially because she works for Virgin Airways and often stops over in America," he went on. "The main thing is for them both to be happy and they are -- they have just hit it off together."
