The fourth time down the aisle might be the charm for Kelsey Grammer — although, as we all know, it won’t be. Yes, RadarOnline reported yesterday that Grammer, 55, is engaged to new girlfriend Kayte Walsh, 29. “They are very happy and very much in love,” says his rep to the site.

The couple met the old-fashioned way — when she was his stewardess on a Virgin Atlantic Airways trip — and started dating while Grammer was still married to wife Camille (who is currently the worst person on “The Real Housewives of Beverly Hills,” which is really saying something).

In addition to a shiny new engagement ring, Grammer also got Walsh a new $6.5 million dollar apartment in New York City.

Lucky girl — the only thing we get out of air travel is unbridled anger, lost luggage and swollen ankles.
