The reality star-turned-shoe designer has made it official by announcing her pregnancy on Twitter.
“Thank you for all the love!! We are so excited for Camden to be a big brother!,” she wrote.
The 26-year-old gave birth to son Camden Jack in August 2012.
During her first pregnancy she told Glamaholic she and her NFL quarterback hubby Jay Cutler wanted to expand their brood to four: “We were talking about the possibility of having another kid right away and then getting married so we can have two kids close in age.
“We want four kids, so we’re thinking maybe have one more, then get married, then have two more,” she added. “But we’ll see — it all depends on how the first one goes.”
And in a shout out to her Hills co-star Heidi Montag, who keeps tweeting about aura babies, Cavallari reveals whether she’s having a boy or a girl is still a mystery.
