Kristin Cavallari had fans cooing over the first photograph of her two-month-old son Jaxon Wyatt on Monday.
The former Hills star took to her new self-named app to share the precious snap of her little son, who is looking sideways at the camera and apparently reaching out to his mum.
Kristin, 27, posted the photo of her little man in a new blog post titled, "Family Time," where she gave an update on her NFL quarterback husband Jay Cutler and nearly two-year-old son Camden.
"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," wrote Kristin.
"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."
The mother-of-two then presented the first picture of her baby son to the world, adding, "Speaking of Jax, here is my precious little peanut."
Kristin also shared a special family photo in which her eldest son Camden greets a goat at his first-ever trip to the zoo.
"Camden's first trip to the zoo, cooking, family time.." she captioned the picture.
The former reality TV star welcomed her second child in May.
Kristin married Chicago Bears quarterback Jay, 30, in a low-key ceremony in Nashville in June last year.
