3rd BBL and I'm 20 lbs overweight- should I lose weight in order to get a Kim Kardashian body?

I got 2 BBLs.Each time 4 litres were removed .First BBl all fat was taken from my back and sides. 2nd BBL my abs&arm pit fat were removed. So far i lost 10lbs but im still 20lbs overweight. Will i have enough fat for a 3rd BBL or should i gain or lose weight. My body looks bigger and i still have not achieved a smaller waist with big projection like Kim K. My waist is 29in after 2nd BBL.I want my waist to be 26 & i want a big shelf like butt.I dont know if i have enough good fat to do this.
