I have a little girl that wants a futuristic, scifi, almost star wars like, cake for her 10th. but it also HAS to be very girly too!! I'm drawing a blank here people!!

I'm drawing a blank too, sorry.

How about a spaceship or other futuristic vehicle, in pink and/or other girly colors. With glittery, sparkly stars all around.

Maybe something like this:

Only in a pink/purple/turquoise color scheme (like a nebula!) instead of the orange and yellow. And probably a different style of rocket, for a 10yo sci fi fan...more like this:
