In round 216 of their never-ending, nauseating battle, Camille Grammer has fired back at her ex, Kelsey.
In mid-May, the former sitcom star filed for custody of the children he shares with the Real Housewife of Beverly Hills.
Now, claiming the actor took such a step "in order to create a false impression to the media and to wrongfully disparage" her, Camille has essentially done the same, submitting documents and fighting for primary custody of kids Mason, 9, and Jude, 6.
In response, TMZ has obtained the legal papers Kelsey has filed in return, which state he has no hope that a settlement will be reached and - once an expert has completed an investigation of all involved - he wants the case to move to trial.
It's an ugly mess, with two young children caught in between.
