The Cavallari-Cutler clan is adding a new team member. 

Former reality star Kristin Cavallari revealed that she is expecting her third child with her husband, Chicago Bears quarterback Jay Cutler, People confirmed. The 28-year-old actress broke the news via Twitter and on her new app. 

"We're at it again! Thrilled to announce baby number 3 is on the way! The Cutler crew keeps on growin'!" she wrote alongside a photo of her making a heart over her growing belly while her two little boys sit in a red wagon behind her.

The couple, who tied the knot with Cutler in 2013 in Nashville, Tenn., are parents to two sons - 1-year-old Jaxon Wyatt and 2-year-old Camden Jack.

After giving birth to her second child last May, the fashion designer told E! News that both of her pregnancies were a breeze.

"I'm lucky," Cavallari said. "Both pregnancies have been really easy for me, I've just been really tired. It's just one of those things where I could literally sleep all day everyday, but I'm snapping out of it a little bit now that I'm in the second trimester."

Last year, Cavallari made headlines for saying that she does not want to vaccinate her children. She defended her decision during her appearance on Bravo's "Watch What Happens Live" with Andy Cohen, saying the outcomes from a vaccination are alarming and unpredictable.
