R&B singer Usher’s STD accuser is with the smoke. Internet celebrity Quantasia Sharpton has allegedly fired shots off at vixen Blac Chyna‘s mom.

A screenshot has surfaced of Sharpton going directly at Tokyo Toni’s Instagram page by threatening to flex her knuckle game.

Last summer, Sharpton publicly revealed receiving multiple death threats since accusing Usher of a sexual encounter.

Days prior, producer Jermaine “JD” Dupri revealed in-studio footage of himself and Ush.

Recently, West Coast rapper Game came to Usher’s defense amid the Internet blowing him up with trolling.

“What people need to realize is, people need to stop worrying about other people’s lives. Most of the people out here talking sh*t and all this sh*t, they probably got herpes too. It is what is is. I ain’t saying Usher’s got this or he got that. Get off his nuts. Literally.” (TMZ)
