WHAT? Please NO! Britney Spears is back, but she is most probably not doing her own dance moves. Tiana Brown, a choreographer’s assistant, was identified as the girl who did Brit’s dance moves as her body double in the music video for “Till The World Ends” (picture above).

Britney is not half the dancer she used to be and that is clear by her “live” performances on stage. She seems to be lacking energy… like she’d rather be anywhere else and doing anything else!

I was actually impressed with “Till The World Ends” because it seems like some of that crazy, wild, dancing energy was back. Apparently it is not, in spite of Britney’s quick dance double denial. This would not be the first time a girl is said to be the pop princess’ double. Remember Allison Kyler?

Check out the video with Britney’s dance moves in “Till The World Ends” below (be warned: there’s only 30 seconds of dancing!). What do you think? Did Britney really use a dance double or didn’t she? Does it matter?
