Kristin Cavallari announced on Twitter today that she is expecting her second child with husband Jay Cutler of the Chicago Bears, and that the family is excited for 18-month old Camden to become a big brother.

Cavallari has said in the past that she wants to expand her family and spoke recently about having Cutler as a partner.

“Having Jay is really helpful,” she said. “It’s important to talk about parenting philosophies before having a child. You want to go in knowing how to raise them to avoid the arguments that can ensue. Being good parents is our top priority.”

The former “Hills” star and fashion designer said last month that they felt they were ready to start trying for another child, and while they don’t know the sex yet, she says she’d be happy with a girl.

“We want to have a second sooner rather than later,” she said. “We know we want another one close in age to Camden and we’re at the point where we’re both ready…obviously, I want a little girl, but if I had another boy I would be so excited as well. I love having a boy. Either way, I’d be really, really happy.”

The 26-year old was noted by several fashion and gossip magazines for her comfortable and chic style during her first pregnancy, so expect to be seeing more of her in the coming months.

Thank you for all the love!! We are so excited for Camden to be a big brother! http://t.co/xCVAGzKdgc
