Kristin and Jay had a brief split after breaking off their engagement in July, but four months later, the parents-to-be got back together. Now they're rejoicing over their exciting news.
"We are thrilled to announce we are expecting our first child together," the couple told People. "It's an amazing time in our life and we can't wait to meet the new addition to our growing family."
"She is really happy," a source told Us Weekly of the former 'Hills' star and 'Dancing With the Stars' contestant. "She is in the early stages, but she can't wait to be a mom. They have just bought a house in Tennessee and can't wait to start their family."
