I think it's safe to say that pretty much all the "pop girls" we argue about fall into the A-list category
B-list would be more like, oh idunno, well-known stars like Chelsea Handler or Rupaul who are masters of their own craft but don't receive the same level of publicity as the megastars
C-list might include singers like Marina, Florence, Bjork, etc.; stars that have huge followings in their own right but whose names aren't really universally known
None of these lists really exist/matter anyway though, so WHO CARES!
