Ronan Keating and his wife Storm celebrated the birth of their first child together and the former Boyzone singer sharing the news in an adorable Instagram post. Keating shared a photo of his producer wife holding their newborn son.

"Incredibly excited to announce the arrival. We're all bursting with love for the newest little member of our family!" he captioned the image.

"Feeling very blessed to be daddy to this little man and the luckiest man in the world to be husband to such a strong, loving and warm-hearted woman and add to my beautiful family #KeatingClan."

The 35-year-old first-time mother also shared a picture of her husband wearing a goofy grin as he held their new addition to the family. "First squeeze #momentcaptured," she captioned the image.

While this is Storm's first child, the 40-year-old singer has three other children – Jack, 18, Missy, 16 and Ali, 11 – with ex-wife Yvonne Connolly.

Jack and Missy shared photos of their first meeting with their sibling. "Welcome to the family bro," the eldest wrote on his social media account.

Speaking to Hello magazine ahead of the delivery, Keating gushed about his wife. "She's going to be an incredible mother," he said. "She's a real Earth Mother. She's a very grounded woman, she's excited about being a mother and she has that natural ability and connection. I'm very excited to see her in that situation. We're over the moon, we cannot wait."

Keating married Storm in 2015 in a ceremony in Scotland after he proposed to her during a romantic holiday in Thailand. The two allegedly tied the knot, five months after the singer's divorce from his wife of 12 years, Connolly has said.
