According to TMZ, Usher is telling his close circle he DID NOT have sex with Quantasia Sharpton because he's just not into her type. In her lawsuit against the Let it Burn singer, Sharpton claims Usher brought her up on stage at one of his concerts, got her number through his security guard, went to her hotel room later that night and had sex with her - without disclosing his alleged herpes diagnosis.
According to the source(s), Usher said it is possible he may have pulled Sharpton up onstage, but doesn't remember. Usher apparently "looks to bring a diverse group of people up onstage, not just supermodels."
