Kelsey Grammer -- 'What You're Reading Is Bulls**t'
Kelsey Grammer is BLASTING reports that he's picking one child over the other in his nasty custody battle with Camille Grammer ... telling a NY photog, "What you're reading ... is bulls**t."
Problem is ... it's not all bulls**t. TMZ published a recent letter from Kelsey's lawyer to Camille's lawyer -- in which Kelsey proposes taking primary custody of their son ... while Camille takes primary custody of their daughter.
Camille rejected the proposal -- and the battle continues.
