Kristin Cavallari is finally getting a little girl.

The former The Hills star turned designer revealed on the Kristin Cavallari Official app she's expecting a baby girl with husband Jay Cutler on Thursday, People reported.

She and the 32-year-old NFL Chicago Bears quarterback are already parents to Camden Jack, 3 next month, and Jaxon Wyatt, 14 months.

"The boys are so excited to have a little sister on the way!" Cavallari, 28, captioned a black-and-white photo of herself holding pink Converse sneakers as her hands rested on Cutler's shoulders.

The former reality TV star announced she's pregnant with her third baby in May.

Cutler and Cavallari -- who also competed on Dancing with the Stars' thirteenth season -- welcomed Camden in August 2012 and then wed in June 2013. Cavallari gave birth to Jaxon in May 2014.

Cutler had proposed a total of three times because they had an on-again, off-again relationship for a while.
