Celebrities love to hide their pregnancies for months (or in Kylie Jenner‘s case, until the baby comes out), but how do they do it? ACE Family YouTuber Catherine Paiz revealed she’s pregnant with baby No. 3 on January 2 by posting a photo of her already-huge bump, and just minutes later she revealed how she kept it a secret despite posting photos of herself on the ‘gram.

“It was so hard to hide my bump on this day,” the 29-year-old wrote on an Instagram Story of a behind the scenes pic from her hubby Austin McBroom‘s “Giddy Up” music video. In the actual video and even other shots from the shoot posted on November 17, there was no trace of a bump, but in the new pic it’s obvious she’s expecting. So how did she make her belly disappear for the cameras?

“I was sucking in on every shot,” she revealed in the Story. “Not to mention I was about to throw up and felt nauseous the whole time.” Yikes! That probably explains why the last photo she posted of herself before her pregnancy announcement was one that only showed the back of her walking down the beach with her family on November 29.

Catherine and Austin revealed the exciting news one day after New Year’s, with Catherine writing, “I wanted to keep you to myself for as long as I could and now after all these months of privately enjoying some time with our family, I am filled with so much joy to share you with the world. You were the missing puzzle piece, I can’t wait to meet you son 💙” Austin followed with his own message, saying, “Dear son, you have an amazing strong beautiful mother, a father who will protect you forever and two beautiful loving princesses waiting for you.”

So far, the happy couple has not revealed exactly how far along Catherine is in her pregnancy, but it’s clear they didn’t wait very long after welcoming their second daughter Alaia in October 2018. The couple also shares an adorable 3-year-old named Elle. If Catherine was already showing in November, we can probably assume she was at least three or four months along then, which would make her 5 or so months along by the time they announced it. And looking at her, she could definitely be even further along. We can’t wait to meet their first son!
