Lavigne struggles to sing and dance

Avril Lavigne

Avril Lavigne has surprised herself by becoming an admirer of Britney Spears, after realising how difficult it is to sing and dance at the same time.

Lavigne has stunned fans by dancing in the video for her new single The Girlfriend and has only just realised why Spears often mimed on stage.

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 realise 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!"
