Maleficent
(2014)

After Malificent (Angelina Jolie) curses Aurora (Elle Fanning), she watches over her while she grows up, developing a fondness for the girl.  

Malificent cannot break her own curse, and Aurora falls into a sleep-like death, when she pricks her finger on a spinning wheel.

"True Love's Kiss" was actually Malificent's own kiss to Aurora's forehead.  

Aurora is now Queen, and her kingdom, along with Malificent's, live in harmony.
