Rapper #KevinGates is getting served ... because his wife just filed for divorce. #DrekaGates, who used to manage Kevin, beelined it to court Wednesday and filed for divorce from Kevin after 9 years of marriage. In the docs, obtained by TMZ, Dreka lists the date of separation as July 10 ... and she’s going with the boilerplate “irreconcilable differences” as the reason for the split. Kevin and Dreka have two minor children — 12-year-old Islah and 11-year-old Khaza — and Dreka is seeking joint legal and physical custody of the kids. via tmz_tv • nathan.berganza
