Maybe the fourth time's a charm?

Kelsey Grammer and his 29-year-old girlfriend, former flight attendant Kayte Walsh, are officially tying the knot...and we hope for Grammer's sake, there's a pre-nup this time!

The couple sparked rumors of an engagement over the weekend when Walsh was spotted wearing a sizable rock on her wedding ring finger at The Kennedy Center Honors gala in Washington D.C.

Grammer's rep Stan Rosenfield tells X17online:

    "They are engaged, and are quite happy. They have been engaged for some time, although I am not sure when as they never announced it to the media."


It's probably safe to say Grammer's recent ex-wife Camille is not too thrilled with the news. The Real Housewives of Beverly Hills star was reportedly ditched for the British beauty this summer -- Kelsey filed for divorce in July after 13 years of marriage, two kids, and no pre-nup.

A wedding date has not yet been announced.
