I have serious doubts it's natural and I have friends with butt implants who think her claims are ridiculous. I have to agree, she used to have a video where it looked pretty clear she had implants, you could see the edge of them. It's odd though that a woman who dies her hair, has acknowledged breast implants, lip injections and tattoos would deny but implants. So maybe she really doesn't. But she looks very unnatural.
And she also appears to be sliding over the edge a la Gemma Massey as well.
