Kristin Cavallari is writing new book "Balancing on Heels."
The 28-year-old former reality TV star announced the project in an interview with E! News on Wednesday.
Cavallari revealed the work will be part-memoir, part-lifestyle book, and is scheduled for release in spring 2016.
"It's basically an intimate look at my life," she shared.
"It's going to be a lot of fashion and beauty. Because I'm such a big health nut, it's also going to be health and fitness. And then a lot of recipes because I love to cook and a lot of mommy and wife stuff. So really just everything in my life."
Cavallari spoke to the website at a photo shoot for her new Chinese Laundry shoe collection, and posted a preview of the campaign on Instagram. She confirmed the new book in the caption, and said she is "beyond thrilled" to share the work with fans.
Cavallari came to fame on MTV reality series "Laguna Beach," and later appeared on the fifth and sixth seasons of "The Hills."
She and Chicago Bears quarterback Jay Cutler have been married since June 2013, and have two children together, 2-year-old Camden and 8-month-old Jaxon.
