Though she has been busy preparing for the birth of her third child and introducing Chicago to the world, Kristin Cavallari did work on her debut book this week. On Tuesday, she wrote on Instagram, “Great first day for the Balancing In Heels shoot all week.”

She updated us again on her progress via Instagram yesterday. “The best part about shooting at my house is I get to have my little peanuts running around,” Kristin wrote. “Shoes are from my line and will be available soon! #BalancingInHeels #bestofbothworlds”

So now we know: Balancing in Heels will include pictures. Evidence that it will include words will be presented when we find it.

This has been 500 Days of Kristin.
