Does Britney Have a Dancing Double? [Video]

So Brit Brit has been doing awesome with her latest album Femme Fatal.  But does she use a dancing double for her music videos??

The honest answer is I have no idea.  When she released her video for 'Hold it Against Me," the rumors started.  They were quickly denied by reps for the superstar.  Then came her latest video, "Til the World Ends."

In my opinion, she isn't shown doing enough dancing to need a double.  I mean most of the shots are of her upper body.  So what is the big deal??  People love drama.  Check out the video for yourself and tell me what you think???
