Hmmmmmm, Girl crush eh? OK, it's a fictitious character ...
Sarah Connor.
Soft and vulnerable and cute in the first Terminator film. (pic 1.)
Fit and tough and badass in the second! (Pics 2 and 3.)
Love her. 
(I am a fan of Linda Hamilton who plays her too.)
Also love Ripley from Alien, Rose from Titanic, Buffy the vampire slayer, and of course Scully from the X Files. I think any strong, positive female role models are fab. That's why I like James Cameron (and his films) so much. He almost always has strong, female leads. 
Agree with the OP about PINK - she is wonderful. Talented, strong, independent, and gorgeous. Ditto Adele (very pretty and talented, and Margot Robbie also very pretty and talented, and Kate Winslet, yep, very pretty and talented.) 
Oh, one HUGE girl crush for me and someone I love.. Madonna. Also love the 21st century version of her - Lady Gaga.
