But it's not what you think!
Sure, he may now be officially divorced from Real Housewives of Beverly Hills star Camille Grammer, but Kelsey isn't applying for a marriage license just yet.
Kelsey and his fiancee Kayte Walsh were spotted leaving the NYC City Hall on Friday after the two attended the wedding of Kelsey's 27-year-old daughter, Spencer.
Sources also say that Kelsey even took Spencer jewelry shopping earlier in the day. Maybe she doesn't get a fancy wedding, but some big diamonds will do!
BTW, Kelsey and Kayte will also be tying the knot at the end of the month. Aw, a double father-daughter wedding. How romantic.
