Kristin Cavallari and her husband Jay Cutler are going to have to buy a lot of pink! The couple took to Cavallari's app, "Kritstin Cavallari Official," to reveal the sex of their third child together, and it's a girl! "Our new addition!" she captions a photo of herself embracing her husband and holding a pair of pink sneakers.

Cutler and Cavallari are already parents to two boys, Jaxon, 14 months, and Camden, 2, according to People Magazine. The 28-year-old "The Hills" star has been married to Chicago Bears quarterback Culter since June 2013, and they have been together since 2010.

"We want four kids, so we're thinking maybe have one more, then get married, then have two more, but we'll see, it all depends on how the first one goes," she tells Glamoholic while pregnant with her first son.

"The boys are so excited for a little sister!!!" she captioned an Instagram picture. "Camden is a really good big brother," the shoe designer told Us Weekly at an event in May. "He's very protective and very sweet, but he also gets a little upset when Jax tries to take his toys and messes with his stuff. He gets a little territorial with some stuff, so it's kind of funny."
