Musicians sing and dance -- we all know this. But that doesn't mean that some musicians don't do it a bit sexier than the rest. And let's not forget all the times our favorite leading ladies in movies have busted a move on-screen, sometimes even involving a stripper pole. These are the sorts of activities we had in mind when putting this GIF collection together. You'll see the best dance moves from Beyonce, Jennifer Lawrence, Shakira, Carmen Electra, Demi Moore, Salma Hayek, Lindsay Lohan, Jennifer Lopez, Jessica Biel, Rihanna, Christina Aguilera and more -- in all of their rump-shaking glory.
