After revealing her second pregnancy in October 2013, Cavallari unveiled the baby-to-be's gender in February. "We couldn't be more excited!" Cavallari wrote via Instagram on Feb 1. Alongside the caption, she posted a picture of a mustache that read: "It's a BOY."
Cavallari previously told Us that her pregnancy cravings weren't unbearable -- "I crave sweet things, but it's no different than when I'm not pregnant" -- but did say she was impatient to meet her future son.
"I feel like I have a bowling ball in my stomach," she confessed to Us Weekly in April, admitting she was "counting down the days" until her May due date.
