Chip Gaines is sharing a hint as to how his fifth baby reached conception.
The father of four shared how their next baby came about in a hilarious tweet, writing, “Hint #3 You might recall a few months back.. the ever amazing, ever romantic @JOHNNYSWIM was in Waco. And they put on a little too romantic of a concert.. anyways, one thing led to another, & we are officially pregnant. And I could not be more EXCITED! #5 #7ThePerfectNumber.”
Before his tweet, Chip, 43, let fans know on Instagram about their pregnancy, writing, “Gaines party of 7… (If you’re still confused… WE ARE PREGNANT) @joannagaines,” along with a photo of the couple cradling his fake baby bump while Joanna, 39, shows off hers under a grey sweater.
