Well we kind of already knew that when her ex Chris Lopez spilled the beans on an Instagram live. But it’s official now. Kailyn partnered with Us Weekly to share a couple of gender reveal photos.

With MTV cameras rolling Kailyn and her 3 sons used confetti blasters? (I’m totally at a loss for what they are called) to reveal the baby’s gender. Which is surprising because kailyn is known for enjoying the surprise of finding out the day she gives birth.

The photos capture her sons’ surprise and thorough enjoyment of the blue confetti!

“The kids and I are so excited to be adding another baby boy into the mix,” Kail told Us Weekly. “Thank you all so much for your continued support & well wishes. Hopefully, the rest of this pregnancy will go smoothly as we anticipate the arrival of our newest addition.”

So there you have it. Kail is once again a boy mom!
