I know she had butt implants not a question of if she had it or not but that was only during the peak of her modelling career. I can tell taht her ass doesnt look the same anymore so she has probably removed them. She had implants in the upper part of her ass to make it pop out more. If you look some of her older pics you can tell that when she sits down you can see where she has implants.
here is a few examples to show you.
You can tell that in the first pic it even looks just like fake boobs does and that is a sign of implants. Also in second pic you can tell that her upper ass has an abnormal shape. Last pic well that is the most obvious. It look just like Nicki minaj which has got implants as well. ( 2 flies with 1 rock )
. Now compare theese to the pics in this forum and its a sealed deal. She has removed the implants now though she dont hav them anymore.
Also here is a pic before she got famous.
kinda big revealer as well.
