Does she have Sagittarius in her chart? I remember reading that she was a Sun in Virgo.

Amy Winehouse has Jupiter/Uranus conjunct in Sagittarius. Also, Neptune in Sagittarius. 

I thought she was a Sagittarius Sun. Had no idea she was a Virgo.

Amy Lee was my first thought when I saw this post. I love Evanescence! I find her music Jupiterian in its expansiveness- powerful vocals and melodies, high-drama themes.

I have the Sagittarius Sun and a Scorpio Moon.  I also have Saturn, Mercury and Venus in Scorpio.  My Sadge Sun is very subdued by my Scorpio planets, but it does uplift me if I get too intense.  

Oh, I forgot to mention that some of those Sagittariuses in those pictures have mental health issues, so there's that! Also, drug addiction!

And two might be psychopaths, LMAO.

But yeah, Sagittarians tend to rebel when they feel too squeezed against the wall. Their rebellion is usually short lived and then they run.....like a horse or a butterfly!
