"We decided to announce that...we're having another boy!! We couldn't be more excited!" the 27-year-old fashion designer posted online on Saturday, February 1.
She and the Chicago Bears quarterback are already parents to their 1-year-old son Camden.
Along with the exciting announcement, Kristin shared an adorable pic of her hubby playing a game of basketball with their sweet boy.
When she first found out she was pregnant again she told E! News she didn't care if she had a boy or a girl the second time around.
"I honestly don't care, I mean there's great things about both. Another boy would be fun, Cam would have a little buddy and then I'd be the woman of the house...but of course I want a little girl, so I don't know. Either one would be great," she said.
It looks like Cam got the little buddy she wanted him to have. Congrats Kristin and Jay!
