Ronan Keating and Yvonne Connolly have both broken their silence after their son announced the arrival of his first child on March 9.
Jack, 23, shot to fame during his short stint on Love Island, and shocked his fans on Thursday when he posted a picture with his baby girl.
Fans had no idea the star was an expectant father, and have all been rushing to congratulate him on the newest addition to the Keating family.

In a black and white snap, Jack is seen holding his little girl, as he captioned it: "Welcome to the world my little [princess emoji]".
Ronan, 46, has since broken his silence by commenting on Jack’s photo calling the adorable newborn a “little cutie”.
Ronan’s wife Storm, 41, also replied with a string of heart emojis, as Jack’s mum, Yvonne Connolly, 48, added: “I miss her so much already”.
His sisters were quick to comment on the post with Ali writing: "Couldn't be happier. So proud of you”, as Missy added: “Cutest little baba. Cannot wait to meet her soon”.
Among the hundreds of commenters were Jack’s fellow Love Island co-stars who also congratulated him on his news.
“Congratulations babes!!!!” wrote Danica Taylor, as Luca Bish added: “Congratulations brother”.
“Congratulations hunny!!!” Paige Thorne commented while Mollie Salmon wrote: “Congratulations Jack, you’ll be the best Dad”.
The identity of the mother of Jack’s little girl has not been confirmed, however, it is understood that he remains single at this point.
He told the Irish Independent earlier this month: “I’m still single and ready to mingle.
“I’m on Hinge, but I don’t use it too seriously. I dip in every once in a while and I’m enjoying being single”.
Boyzone star Ronan shares three children with his ex Yvonne – Jack, Ali, and Missy – as well as an eight-year-old son, Cooper, and two-year-old daughter, Coco, with wife Storm.
