Avril & Britney - United in Dance

Avril "Spitter" Lavigne surprised her fans by dancing in her new video "The Girlfriend" and apparently she realizes how tough it is to sing and dance at the same time. So in the same explanation she both compliments and disses Spears:

She says, "I've had to work with a choreographer, but I'm actually quite athletic and I have good rhythm so it comes natural to me. It made me appreciate people like Britney Spears, as I realize how much work goes into that stuff. The whole thing where you sing and dance is so hard, so that's probably why she doesn't sing, right, ha ha!"
