Definitely agree with Anna Kendrick!
Lzzy Hale has shot up to the top of my list. I've gotten addicted to Halestorm, great music and she's got a killer voice, and good lord she is ridiculously attractive lol. You can kinda see her belly button in the music video for Love Bites through a see-through shirt, but it'd be nice to find a pic that's in color (who video's in black and white).
What really sucks is she's clearly wearing an outfit that shows her whole stomach in the video for I Get Off, but she's either sitting behind a table or the camera's not low enough for pretty much the whole video. There's one very brief and blurry shot of her navel. :/
