In 2011, Kristin Cavallari—whose debut memoir Balancing in Heels (f.k.a. Balancing on Heels) is due out in 321 days—competed as a Star on the 13th season of Dancing with the Stars. She was the third contestant to be eliminated, besting only Metta World Peace and one of George Clooney’s ex-girlfriends.

On Thursday evening, Kristin Cavallari announced via Instagram that her forthcoming baby will be a girl. “Our new addition!” Kristin exclaimed in the caption of photo of her holding little pink sneakers. “The boys are so excited to have a little sister on the way!!!”
