Kristin Cavallari may have been a part of one of the most memorable TV trios to date -- with Laguna Beach natives Stephen Colletti and Lauren Conrad -- but the erstwhile MTV starlet will soon have her very own group of three. That's right: The "Hills" alum and her NFL hubby Jay Cutler are expecting baby No. 3! And the pregnancy announcement is a pretty heartwarming one to boot (no pun intended).

"We're at it again! Thrilled to announce baby number 3 is on the way!" the shoe designer revealed on her app under the headline "Big News," along with the smiling snapshot above with her two cutie pie sons -- two-year-old Camden and one-year-old Jax -- happily seated in a wagon in the family's backyard. Big bros in tow!

"The Cutler crew just keeps on growin'!" she added with a heart emoji. You can say that again, K-Cav!

While the blond beauty didn't dish any details about the bundle of joy's gender or her due date, the future author did debut her teensy weensy bump -- while giving her bun in the oven a bit of love. Will the boy streak continue for the Cutvallaris -- allowing them to form their own mini football team -- or will the SoCal native have a mini-me of her own? Mother-daughter duo wearing black chokers?! Time will certainly tell!

Offer your congrats to the future family of five in the comments below!
