Actress and designer Kristin Cavallari has announced that she and her husband Jay Cutler are expecting their third baby.

The 28 year old former star of ‘The Hills’ and 32 year old Cutler announced the good news on Monday via the Kristin Cavallari Official app, but first they teased the news a couple of hours beforehand on Instagram.

She then posted a photo on the app with her hands over her belly in the shape of a heart, with her two children in the background, writing “We're at it again! Thrilled to announce baby number 3 is on the way! The Cutler crew just keeps growin'!”

Cavallari began her acting career in 2004 when she was still at high school, starring in ‘Laguna Beach: The Real Orange County’ for 28 episodes until 2005. She has been a guest judge on ‘America’s Next Top Model’ and a contestant on the 2011 season of ‘Dancing with the Stars’.

Since becoming a mother, however, her acting career has gone on to the back burner, and she now largely concentrates on design. In September 2014, she told Line magazine that her inspiration was Kate Moss, describing her as “[my] ultimate style icon. I've never seen a bad outfit on her. She's so effortless and chic and nails street style.”

Last year, just after she gave birth to her second child, she attracted national criticism when said that she refused to have them vaccinated because of a fear of a connection to autism.
