French Montana SUED By Waka Flocka’s Mom — Don’t Step Out On Me!

Exclusive 0315-debra-antney-french-montanaWaka Flocka“s mother and famed rap manager Debra Antney does NOT take kindly to being two-timed … and is now suing her client French Montana, claiming he made several lucrative concert deals behind her back.

According to the lawsuit, Antney — who runs Atlanta-based management company Mizay Entertainment — entered into an exclusive management contract with French in November 2010.

Antney announced the new partnership with several press releases, and French himself acknowledged the relationship … praising Antney”s management skills, telling XXL, “As far as management, she got it down pat.”

But in the lawsuit, Antney says things quickly went sour … claiming French subsequently secured several concert appearances without her knowledge or consent, cutting her out of a 20% management fee.

Antney — who used to rep Nicki Minaj — is now suing for unspecified damages, totaling at least $50,000.

French was served with the lawsuit while entering an Atlanta concert venue on Tuesday. Calls to French”s camp were not returned.
