she actually just said she twerked way before miley , and maybe she has watched her doing it,that's all.In my opinion it wasn't even dragging her , she probably pissed that NOW twerking has become so much "famous" thanks to miley
She never said she invented twerking, she simply states that she's been doing it long before Miley. I bet you the interviewer took it out of context like they always do.
