Amber Rose's Butt Comes Up in Manslaughter Trial: Defendant Claims She Gave Amber Injections!

Amber Rose's rear is often the topic of conversation, but in a courtroom? This is new.

The famous curvy celeb and her equally famous derriere was brought up during the testimony of Gothic hip-hop artist Padge-Victoria Windslowe, who has been charged with killing a London breakdancer with illegal butt injections, according to MSN.

Windslowe, who also goes by the nickname Black Madam from her years of running an escort service, took the stand Friday in a Philadelphia court and dropped Rose's name when talking about some of her notable clients.

She alleges Amber went in for butt injections before she became famous and "was like a walking billboard," for Windslowe's booty-plumping work. "She brought a lot of girls from VH1."

She said under cross-examination that the star's ex-boyfriend Kanye West dropped Rose off for one procedure when the two were dating and that she was supposed to perform a "correction" on Nicki Minaj, but that never ended up happening.

The 45-year-old, who has been doing this service for 20 years now, told the court,  "I was the best, and I don't mean that to be cocky."

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.
