Kristin Cavallari Shares First Photo Of Son Jaxon: See The 'Precious Little Peanut'

The former 'Hills' star shows off her adorable 2-month-old, plus some family pics.

Kristin Cavallari's baby is ready for his close-up.

Two months after giving birth, the former "Hills" star showed off her adorable baby boy, Jaxon Wyatt, for the first time. Posting the cute shot on her own Kristin Cavallari app, Jaxon -- born on May 7 -- looks right into the camera as he lounges on a rug surrounded by a bunch of his toys.

Kristin also updated everyone on how much her life has changed since her family of three -- she is married to NFL star Jay Cutler and has a 23-month old son, Camden -- became a family of four.

"The end of June through the end of July is my favorite time of the year, because Jay isn't working and we use those 4 weeks to relax and spend as much time together as possible before he takes off for training camp and the football season begins," she wrote. "This year we took Camden to the zoo for the first time, I cooked up a storm, we had family in and out, and most importantly we adjusted to now being a family of 4 with baby Jax. Speaking of Jax, here is my precious little peanut..."

Kristin then posted a bunch of photos, including son Camden playing at the zoo and herself cooking homemade pizzas, having a date night with her husband and designing shoes for her 2015 spring collection.

The former reality star also showed off her post-baby body, which she's been working hard for. Kristin revealed to E! News that she recently lost 20 pounds in just two months working out four or five times a week.
