Bump's out, and Kristin Cavallari's proud! The former Hills star took to Instagram on Saturday, Jan. 18 to show her second pregnancy's progress in an all-black workout ensemble.
"Gym selfie….baby bump getting big!" she captioned the picture.
Cavallari told Us Weekly that for Christmas, their doctor put a note with their second child's gender in it, and they opened it on the holiday. But they have since remained silent about the child's gender on social media.
In September 2013, Cavallari told Us Weekly, "I would love to have a little girl, but if i had another boy, that would be great too."
