Rapper French Montana is facing legal action from his manager over allegations he inked a number of lucrative concert deals without her knowledge.

Debra Antney has accused the hip-hop star of breaking an exclusive management contract he signed with her company Mizay Entertainment in November 2010, reports Tmz.com.

Antney, who is mum to rapper Waka Flocka Flame, is suing for unspecified damages amounting to at least $50,000 (£31,250), claiming Montana cut her out of her agreed 20 per cent fee by negotiating gig bookings without her consent.

Montana, real name Karim Kharbouch, was served with the lawsuit as he entered a show venue in Atlanta, Georgia, on Tuesday (12Mar13).
