She's grown up already. Avril Lavigne shows her mature side by posing topless for the June 2007 issue of Blender magazine. Well, yes many assumed she really goes topless, but the truth is that she doesn't.

The singer, as apparent on the magazine's cover, takes her top clothes off with more pictures inside show her drinking in one angle and smoking on the other. In fact, she's not topless on the cover and was instead wearing a tube top, on which the magazine put a banner on top of it.

Take a sigh Avril fans for she isn't that bad and is still the one innocent and cute yet wild on stage you used to know. All in all, still she thinks "The Blender shoot was really fun because it was super rock and roll, we had a bottle of [whiskey] and ate cupcakes. Everyone was super cool. It was definitely a different kind of photo shoot for me."

Avril, a punk singer, sat down with Blender to discuss the writing of her single "Girlfriend," boys, booze and the pursuit of happiness.
