I used to think Britney was the most incredible dancer, just because of what her fans always say.
Then I watched some of the videos they posted, just for the hell of it.
She does nothing difficult. She puts on sexy stripper moves, tosses her hair around, shakes her **** and moves her belly. Nothing astounding. It's more like stripper dancing than actual dancing.
unless Britney does some serious pre-2007 dancing then Lady Gaga. But If Lady Gaga lip-synced she could even beat old school Britney but thankfully she doesn't.
