The Celebrity Love Island contestant wants the operation to correct a mistake made during her 13th round of surgery.
Douvall told Heat: "I know it will kill me. But I'd rather die trying to sort things out."
She continued: "My last boob job was a disaster. One of the implants left my chest really lumpy, so I needed to sort it out."
Earlier this year, Douvall revealed that her daughter Georgia, 13, had requested a boob job for her birthday.
The glamour model admitted she would pay for her offspring's surgery when she turns 16.
