The model, who is married to Ice-T, appeared on the US TV show The Doctors to prove once and for all that she hasn't had "butt implants".
A televised ultrasound of the star's ample bum was performed by a guy in a white coat called Doctor Andrew Ordon.
The doc's verdict: "Coco's buttocks are 100 percent real!"
Check out the footage above.
Coco isn't the first celebrity to call on a medical professional to disprove rumours of plastic surgery. Courtney Stodden had a similar procedure performed on her breasts last year.
