Amber Rose has been named as the butt implant client of Gothic hip hop artist Padge-Victoria Windslowe, whose nickname is Black Madam, the Associated Press reports via MSN.

Windslowe has been charged with killing a London breakdancer with illegal butt injections. Windslowe recently issued a testimony about her butt injections and named Amber Rose as her notable client.

Windslowe claims she gave Rose butt injections prior to her fame and, since then, Rose has been a "walking billboard" to promote her illegal service. Windslowe alleges that Rose even recommended her to many VH1 reality TV stars.

According to Windslowe, Rose's then-boyfriend Kanye West was privy to Rose's butt injections and dropped Rose off for one procedure while the two were dating. Windslowe claims that Nicki Minaj was also supposed to be one of her clients but bailed on a correction procedure she had asked Windslowe to perform.

"I was the best, and I don't mean that to be cocky," Windslowe said during her testimony.

Windslowe is charged with third-degree murder in the 2011 death of Claudia Aderotimi, who was injected with low-grade silicone at a Philadelphia airport hotel, says E! News.

So far, neither Rose nor Minaj have responded publicly to Windslowe's claims.

News of Rose's alleged butt injections comes just days after her ex-husband, Wiz Khalifa, denied on Twitter that he had cheated on Rose during their marriage.

In addition to calling Amber out on her wrongdoing, Khalifa also took to Twitter to show photos to prove their son, Sebastian, was not present at the birthday party Khalifa threw for him.

TMZ suggests Amber kept Sebastian away from the party out of spite.

"Amber was supposed to bring Sebastian to the party, and they would celebrate his birthday together ... as parents. Wiz says everyone was there and he's heartbroken the boy couldn't celebrate with civil parents," a source said.
