Storm and Ronan have been married for three years and welcomed young Cooper in 2017.
The Boyzone singer is also dad to Jack, Missy and Ali from his first marriage.
The pretty blonde spoke to WHO about welcoming her firstborn, saying, “Having a baby was the greatest blessing of my life.”
“I had to have an emergency C-section and I look at my scar – and I know scars aren’t meant to be pretty – but I look at it with so much pride. My body’s changed, I’ve changed, our life has changed, but I think it’s just the greatest thing in the world.”
Meanwhile, the proud dad would love to add to his brood.
“We definitely would,” Ronan revealed.
“Right now, we’re really enjoying Cooper and his age. I don’t think we’d want to change anything with that but yeah, of course – please God – down the line.”
“That would be lovely,” Storm added.
