R Kelly's Ex-Wife Hits The Pole...(PIC)

R. Kelly's ex-wife Andrea -- who met him in 2002, had three of his children and then divorced Kelly during his child pornography trial -- has hit the pole to teach Chicago folks how to dance all sexy and stuff.

Andrea has a lot of experience, as the former choreographer of Kelly's stage shows and videos. She recently launched a burlesque show called Le Pink Kitty Cabaret.

Kelly will be teaching dance workouts such as "Hooker Heels" and schooling her students on the art of seduction.
