Ronan's fashion designer wife also shared the same photo with her Instagram followers, adding the caption: "A beautiful calm birth thanks to Claire Mellon and all the wonderful team at @theportlandhosp Thank you so much for taking such great care of us ♥️ Coco Knox Keating, born 27.03.20 #myheartcouldburst #ourlittlegirl"
The loved up couple— who tied the knot in 2015 five years after meeting in 2010— revealed they were expanding their brood in November.
"I’ve always wanted at least one of each sex so I’m feeling very blessed. That’s five kids in total now, so that’s enough, we’re going to have to get Ro to have the snip," she joked.
The blogger and Irish musician— who rose to fame in 1993 when he joined Boyzone— welcomed their first child together in 2017, telling WHO "having a baby was the greatest blessing of my life."
While this is Storm and Ronan's second child together, he also shares three children, Jack, 20, Missy, 18, and Ali, 14, with his first wife, Yvonne Connolly.
