Ice T's wife Coco has a fake booty:
She has implants. They also call it a brazilian butt lift. Hard silicone implants are placed under your butt cheeks to give your booty a rounded / lifted shape.
The silicone injections are bad news. It's like back alley plastic surgery. I hear horror stories about girls getting fucked up with that shit, it's a real bad problem here in FL, especially around the miami area.
