I think that might have been a screencap from one of the mtv interviews. But I'm not sure.

The icon was from someone's m&g in Chicago. I remember reading and seeing that pic in her review from her personal lj post as her icon. She said she wasn't giving a fullsize of it.
I think the Spin picture was only that size. I only found this one.
