WHO CARES???  She looks great still and there really wasnt any amazing dance moves in this video that would make me believe a body double was required. Seriously, could the paparazzi try any harder to make it look like she is a has been?  How far will those losers go, how desperate can they be to come up with something this weak to try and sell their pictures and baloney?  Really, get a life and stop being so jealous that she and other stars earn their money honestly rather than like them acting like parasites trying to take advantage of minor problems or hiccups in their lives!
