Hitting back: Iggy has persistently denied having butt implants and insists that the only plastic surgery she has had is breast implants and a nose job 'Her shape and personal history makes me think she has,' he said, adding that telltale signs of a Brazilian butt lift include: 'A very small waist and big buttocks. Also, tiny scars in the lower buttocks creases, they are usually very hard to find.' A Brazilian butt lift is a form of buttock augmentation, which enhances the size and shape of a patient's bottom using a fat transfer from other areas of the body. Iggy, who is often hailed by fans for her womanly curves, previously told Sway Calloway on Sway in The Morning that her bottom is completely natural.
