Four hundred and ninety days until Kristin Cavallari reveals "really just everything in my life" in her debut book, Balancing on Heels. Four hundred and ninety days we must wait to crack the spine of that freshly-bound hard(?)cover and read, read, read, all the thinks Kristin has ever thought during her existence on this planet, including what she is obsessed with, and whether or not that thing is a hat.

Kristin did give us a peek into her gray matter today, however, with this Instagram post.

She captioned the photo, "Yes I'm obsessed with this hat and wear it all the time."

So I guess now we know Kristin's thoughts, which are: "I'm obsessed with this hat."

This has been 500 Days of Kristin.
