The mother of two, Jaxon and Camden, added, "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 has been pretty busy within the last few months since the arrival of Jaxon, telling E! News how she has managed to lose 20 pounds since the baby was born.

"I started working out when Jax was three weeks old," she told the news site. "I've been working out four to five times a week for 30 to 45 minutes at home, doing tons of leg work likes squats, lunges and lifting weights. I want to start Pilates again to focus on my core. I'll probably get back into it in the next couple of weeks."
