Kristin Cavallari has opened up to People magazine about her busy daily routine days ahead of the launch of the new collection for her Chinese Laundry shoe line.

The former "The Hills" star turned shoe designer illustrated her jam-packed days with a series of pictures she shared with the publication. The snapshots document everything from her made-overnight breakfasts to her Pilates sessions.

"When I'm pushed for time in the morning I make overnight oats," she said of her breakfasts. "I put rolled oats, almond milk, agave and whatever else I'm feeling together and put it in the fridge overnight. I made these for me and Camden."

Camden, 4, is Cavallari's elder son with Chicago Bears quarterback Jay Cutler. The couple welcomed their second son, Jaxon, in May of this year.

"Pumping in the airport bathroom," Cavallari captions a photo of baby Jaxon's morning meal. "Not easy being a breastfeeding mom on the go!"

"Stretching it out in a Pilates session," she wrote alongside the last image, which finds her hanging from two bars at the gym.

Cavallari is currently planning the launch party for her Spring 2015 Chinese Laundry collection. You can check out a preview from her line on the video below and the full shoe collection here.
