The former lovers are currently locked in a bitter and highly-publicised court battle as they fight for custody of their young daughter, Lucia.
Gibson hit headlines earlier this year (10) when the Russian singer accused him of violently beating her and knocking out her teeth in an alleged altercation, while taped recordings of their bitter arguments were leaked on the internet.
According to TMZ.com, Judge Scott Gordon has warned the Grigorieva going public with her story could negatively impact her custody battle.
However, the website reports Grigorieva has defied the warning by sitting down for an hour-long interview on Larry King Live on Saturday night (13Nov10) with one of her lawyers, Marty Garbus, to "speak out on behalf of battered women".
Reports suggest Larry King played portions of a number of the tapes Grigorieva allegedly recorded in secret, in which a man purported to be Gibson can be heard hurling insults at her.
Executives at King's TV network CNN had yet to confirm a broadcast date for the interview as WENN went to press.
