Boyzone star Ronan Keating became a grandfather at the age of 46. This became known after his son, “Love Island” star Jack (23), surprisingly announced the birth of his daughter. On Thursday evening he shared a first snapshot of himself with his newborn in his arms on Instagram. “Welcome to the world, my little princess,” he lovingly wrote.

Jack Keating has not publicized a romantic relationship since he moved out of the “Love Island” mansion last summer and it is not known who the baby’s mother is.

For the musician Ronan Keating – himself a father of five children – it is the first grandchild. He commented on his son’s post: “Little cutie” and a red heart. Jack’s sister, Missy Keating, 22, also posted an affectionate comment: “The cutest little baby. Can’t wait to meet her soon.” Ronan Keating’s second wife and Jack’s stepmother, Storm Keating, 40, responded to the post with a series of heart emojis.

The Irish singer has eldest child Jack with ex-wife Yvonne Connolly, 48, who is also mother to Missy and Ali, 17. Their marriage lasted twelve years. Yvonne wrote on Jack’s post: “I already miss her so much.” Ronan Keating has been married to Australian fashion designer Storm since 2010. The couple have children Cooper, 5, and Coco, 2.
