Lady Gaga and Miley Cyrus both caused quite a stir with their recent on-stage twerking antics.
Miley's was much earlier this summer and people are still talking about it as the singer engaged in some R-rated dance moves with Robin Thicke during their "Blurred Lines" mashup.
As for Gaga, hers was just this weekend when she twerked with R.Kelly on this week's episode of Saturday Night Live during their performance of "Do What U Want."
Surely by now, you've seen both performances, so the question is: whose was racier?
Lady Gaga and R.Kelly or Miley Cyrus and Robin Thicke?
