THE BIGGEST BREAST. Brazilian model and television personality Sheyla Hershey received the world's largest breast implants by getting her bust to a staggering size of 38KKK. Despite spending approximately $395,000 on her surgeries and almost dying four times in the process, the model insists on once again going under the knife. She is reported to be getting expanders fitted in her chest which will be filled with 24,000cc of saline, achieving OOO cups. The 39th boob operation is part of her hopes. To date it is understood that the model has had 38 or 39 breast surgeries, 28 liposuction surgeries, five nose jobs, 190cc butt implants, two floating ribs removed, two tummy tucks, one eyebrow lift, numerous botox and fillers, two ribs removed, and 360 liposuction and tummy tuck and fat transfer to hips (if she has undergone this OOO boob job).
