Fifty days after announcing she would produce a book in the next 500, Kristin Cavallari has provided evidence of her work on said book for the first time. Or rather, she has at least provided evidence that somebody has typed up some pages that may someday be a part of a book called Balancing on Heels by Kristin Cavallari.

Kristin posted the photo below with the caption, "Working away...can't wait for u guys to read Balancing On Heels [thumbs up emoji]."

Looks like the book will cover a LOT of topics.

This has been 500 Days of Kristin.
