Kelsey Grammer -- My New Wife Likes Men

In what sounds like an obtuse shot at Camille, a bushy Kelsey Grammer told our photog last night ... beards were not favored in his old household, but now they're welcome because new wife Kayte likes real men.

Kelsey could be taking a shot at Camille and her new boyfriend ... who is eight years her junior.

So now they're fighting over beards.
