Michael Jackson's ex-wife is set to marry Jackson's former close friend and business associate ... but turns out there's a small problem -- he's already married.
Marc Schaffel is engaged to Rowe though a date for the wedding has not been set. Turns out ... Shaffel married model Kerstin Christa Nissen in 1992. According to legal docs -- obtained by TMZ -- they separated 8 months later but never got divorced.
Shaffel got around to filing papers last week, citing irreconcilable differences.
It generally takes 6 months for the divorce to become final, so Rowe will just have to cool her jets.
My Fiance is Already Married!!!
