Slim cute, photo model Sister Derbie has decided to get some increase at her Backside and is already putting in the necessary work to make that happen.
Her former rival, Fella Makafui beat her to that and it was perceived that is why Medikal left her for Fella, though he has cleared the air saying it was not.
In a video sighted online, the photo model is seen working out and doing some squats, which widely encouraged if one wants an increase with her backside.
Sister Derbie did the workout and hilariously said in the video, if you add banku to the work out it will yield positive results.
Many are wondering if the photo model is no more happy with her slim cute figure, which most people love about her or she is just doing a normal workout just to keep fit.
