She's pretty short but still has a KILLER bod! As for her music, I actually think that, while it's certainly not the most original stuff, it's better than a lot of American pop music these days. I'd listen to any of Alizee over Britney or Christina. It comes off as cute yet clever, with a dash of sexiness for sure!
Here's what I found of her on YouTube. When she's in that sailor suit, with those thigh-high boots, well that's gotta be one of the sexiest performances I've ever seen. Extremely sexy. And towards the end of the performance we get a bit of a payoff, too!!!
