Ronan Keating has taken to his Instagram to announce the arrival of his newborn son.
He posted a snap of his wife Storm and the bub with the caption, "Incredibly excited to announce the arrival. We're all bursting with love for the newest member of our family."
The singer gushed, "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."
Storm later shared on her Instagram a pic of her hubby holding their new baby with the caption, "First squeeze."
The couple are yet to reveal the name of their adorable bundle of joy.
It's the couple's first child together, with Ronan already a father to children Jack, 17, Missy, 15 and Ali, 11, from his first marriage to Irish model Yvonne Connolly.
The couple met back in 2010 on set of Australia's X Factor where Ronan was a judge and Storm was a producer.
They tied the knot in August 2015, with Ronan sharing to News.com.au, "I’m happier than I’ve ever been. Storm makes me feel secure. It’s very refreshing. I haven’t had that before."
