Moore filed a police report after her altercation with Williams, and the raw footage of their dustup led to misdemeanor battery charges against Williams. The fight happened in late March, when the reunion special was being filmed.

Williams plans to retaliate by filing felony aggravated assault charges against Moore, TMZ reports.

The three-part Real Housewives of Atlanta reunion special begins Sunday at 8/7c on Bravo.
