It's a happy week for Ronan Keating and his wife Storm as they have just welcomed into the world their first child together. They shared their first image of their bundle of joy on social media, and other members of the family have also been expressing their joy.

The former Boyzone star, who is married to 35-year-old TV producer Storm Keating (nee Uechtritz), posted a snap of his wife and their new baby boy on Instagram today (April 27th 2017). His two teenage children also posted their own pictures.  

'Incredibly excited to announce the arrival', said Ronan in his photo caption. 'We're all bursting with love for the newest little member of our family! 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.'

Storm also posted a black and white picture of Ronan holding his son with a big smile on his face and his eyes tightly shut. She captioned the image: 'First squeeze'. Just one day ago did she post a picture of her Louis Vuitton bag all packed and ready to go. 'They say to have it ready just in case...' She said at the time.

The 40-year-old Irish singer is already a father to three other children from his marriage to Yvonne Connolly. After marrying in 1998, they had Jack (18), Missy (16) and Ali (11). The pair separated in 2010 but did not finalize their divorce until 2015, just 5 months ahead of his marriage to Storm.
