The Disney princess has been given a make-over for the new Wreck-It Ralph film – with one bizarre tweak.

She may be 68 years old, but Disney's Cinderella doesn't look a day over 21.

Somehow, the loss of both her parents and a life of servitude, drudgery and maltreatment didn't dim her youthful glow.

But even doe-eyed Disney princesses with improbably teeny waists aren't free from imperfections – the perpetually perky Cinderella has her flaws, too.

The Wreck-It Ralph movie is being released later this year, and some new characters have been unveiled, including a 3D version of Cinderella.

As well as apparently getting a feminist make-over, the updated Cinderella also looks different, thanks to one simple tweak – her ears. She used to have no ears!

In the 1950 classic, we see her in her sparkly blue ballgown with her hair swept up, but no ears. Even when she's in her rags, her ears aren't exactly well-defined. One eagle-eyed fan pointed out the difference on Twitter, and others were quick to express their astonishment at having never noticed.
