Avril LavigneAvril LavigneShe's gone from punk chick to grown-up glam.

And with the new look also comes a more sophisticated persona...

After swapping her skater duds for a more mature image, Avril Lavigne is now having a good laugh at her younger, rebellious past.

She told Arena magazine: "When I look back now all I can think is, 'God, I was such a s**t'.

"I was such a tomboy, running around, getting in fights, hanging out with guys.

"In all my interviews I would have my head down and moodily just grunt an answer.

"I look back and laugh now as I realise how much I've grown up. But that was my style back then, that was me."

The 22 year old told the mag: "I'm still a kid at heart, but now I'll wear tight pants or heels, whereas before I was like, 'There's no way you're getting me in a skirt'.

"I still have a rock 'n' roll look... I'm just more rock-glam these days."
