A picture of what appears to be R&B singer Keyshia Cole Gibson performing fellatio has set the Internet on fire. The image is currently being circulated on Twitter, but Keyshia is firing back, claiming the image is not of her.

PICTURES: Keyshia Cole Lookin’ Sexy In The City!

“Evil a** haters STAY on some bullsh*t! Y’all wish! Lol!” she tweeted late Wednesday night, adding, “Let em have fun! They seem to enjoy being filth, I say let emm talk! RT @eman_amg: That’s not @KeyshiaCole nose Or tattoo … get off that.”

But the singer and reality star’s tone turned more serious on Thursday morning after the picture spread further. “People that have no self respect, you worship! Folks that have a child, a husband, hustled from the bottom up, y’all try to tear down. Shame.”

RumorFix has checked out the picture, and it does not appear that the singer has a tattoo in the same location as the woman in the photograph.
