TMZ broke the story ... Camille Grammer wanted custody of the former couple's 2 kids because Kelsey wanted to split them up. Kelsey's lawyer told us her story was "inaccurate." But we've obtained a letter Kelsey's lawyer sent to Camille's attorney which says exactly what Camille claims.
The letter, dated April 29, 2011, says "Kelsey proposes ... Kelsey shall have primary physical custody of Jude and Camille shall have primary physical custody of Mason." The letter says Kelsey wants to enroll 6-year-old Jude in a Chicago school.
The letter also outlines very specific terms of the custody agreement, including when each parent gets the kids on holidays.
Camille filed for primary physical custody yesterday ... and we've learned she wants custody so the kids aren't separated from each other.
As for Kelsey, his rep, Stan Rosenfield, tells TMZ, "Despite the fact that those connected with Camille Grammer seem to be hand delivering confidential documents to TMZ and other media outlets, we will continue not to make public statements about their private matters which can and apparently does beg for misinterpretation."
Rosenfield continues, "There is no valid reason to drag the Grammer children into any media spotlight."
