Star of The Hills reveals she’s expecting a baby girl

A little sister is on the way! Congrats are in order for Kristin Cavallari and Jay Cutler who revealed yesterday that their third child will be a baby girl. The couple already have two sons together, one-year-old Jaxon Wyatt and three-year-old Camden Jack.

As with her pregnancy announcement back in May, Kristin announced her happy news via her official smartphone app, rather than on social media.

Posting a black-and-white picture of herself hugging Jay while holding an adorable pair of pink baby Converse, the former reality star wrote, "Our new addition! The boys are so excited to have a little sister on the way!!!"

Kristin's original pregnancy reveal was equally as sweet, with the mum-of-two sharing a snap of her holding her hands over her tiny bump as Jaxon and Camden sat behind her in a red wagon:

"We’re at it again!" she wrote at the time. "Thrilled to announce baby number 3 is on the way! The cutler crew just keeps on growin'!"

Kristin and Jay first starting seeing each other in 2010, and got engaged in spring 2011. After a three month break-up, the couple got back together in November 2011 and welcomed little Camden a year later.

The blonde beauty rose to fame when she appeared on MTV's Laguna Beach back in 2004 along with her high school classmates Lauren Conrad, Lo Bosworth and Stephen Colletti. In 2009 she replaced Lauren as the lead character in the show's spin-off series, The Hills, which ran until 2010.

We can't wait to see the first pictures of her new arrival!
