Joanna and Chip, 43, shared their exciting news with a hilarious snap featuring Joanna’s baby bump and Chip dressed in a similarly colored shirt, poking his own belly out while his wife places a hand on it.

“Gaines party of 7 … (If you’re still confused … WE ARE PREGNANT),” wrote the fifth-time dad-to-be, who shares sons Duke, 9, and Drake, 12, plus daughters Emmie Kay, 7, and Ella Rose, 11, with Joanna.

Following their Tuesday reveal, Chip used Twitter to confess how baby No. 5’s conception became a reality — and it was all about the romance (and the music).

“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,” he wrote.

“Anyways, one thing led to another, & we are officially pregnant. And I could not be more EXCITED! #5 #7ThePerfectNumber.”
