Kristin Cavallari is going to welcome a new addition to her growing brood.

The former reality star shared the news on her app Monday, writing, "We're at it again! Thrilled to announce baby number 3 is on the way! The Cutler crew just keeps on growin'!"

Cavallari, 28, also posted a sweet photo of herself making a heart shape with her hands in front of her not-yet-visible baby bump, while her other children sat in a red wagon behind her.

She and Chicago Bears quarterback Jay Cutler, who were married in 2013, already have two sons together: Camden, 2, and Jaxon, 1.

Earlier this year, the busy mom gave fans a glimpse into the couple's fast-paced life, posting a series of funny texts from her husband, who was anxiously awaiting her return from a trip.

"Need u home asap," read the first text. "All hell has broken loose. Jax is in his crib. Cam refuses to eat. I'm about to leave."

Hopefully, Cavallari's third pregnancy will go as smoothly as her previous two.

"I'm lucky," she told E! in 2014 when she was pregnant with Jax. "Both pregnancies have been really easy for me, I've just been really tired."
