"We want to have a second sooner rather than later," Cavallari said. "We know we want another one close in age to Camden and we're at the point where we're both ready."

Cavallari, who married Cutler in June, said that initially, she thought she'd get pregnant six months after giving birth to Camden but, "I definitely wasn't ready," she said. "Now, I'm finally ready."

"Obviously, I want a little girl, but if I had another boy I would be so excited as well," the new mom continued. "I love having a boy. Either way, I'd be really, really happy."
