Love Island’s Jack Keating faced a nervous wait last year when his little brother was rushed to hospital with a "mystery illness".
Jack, 22, the oldest son of pop singer Ronan, is one of the new boys sent to stir things up in Casa Amor.
But while he must have felt butterflies in his stomach before making his entry to the Majorcan villa, it was nothing compared to last September’s frantic dash to A&E with four-year-old Cooper.
Dad Ronan told the Mirror that his heart broke as he watched his “little fella” in distress, hooked up to oxygen.
He added: “It was frightening. You’d give anything to get them back and healthy.
“You’d sacrifice anything to make sure your kids are OK.
“I’ve been through the process of going to A&E, and spending four hours in the waiting room, then spending two nights in the hospital, my heart just breaking, their little faces on oxygen.”
“He just had a respiratory thing and was fine. It wasn’t anything serious in the end but it was serious enough that we had to go to A&E.
“The staff were fantastic, the way they look after the kids. But what us parents have to go through, it breaks your heart.
“We’re lucky, we’ve five great healthy kids, but especially at this time of year and after the year we’ve had, any little cough and you’re paranoid, it’s scary.”
Jack is one of three siblings, along with Missy, 21, and Ali, 17, Boyzone star Ronan shares with his first wife Yvonne Connolly, with whom he was married from 1998 until 2015.
Cooper, and two-year-old sister Coco, have a different mother, Storm, who the singer married in 2015.
Following the drama with Cooper, Ronan, 44, shared photos of his son in hospital, writing: “Not the 24hrs I had imagined. But ya never know what life has in store…. This little guy is an absolute trooper. I’m blown away with his strength and charm. Mum & Dad are a mess worried sick and he takes it in his stride.”
The family struggled with yet another medical emergency in March last year after Storm, who he met in 2011 while a judge on the Australian version of X-Factor, where she worked as a producer. was left temporarily paralysed with a rare spinal cord condition that could have left her unable to walk again.
She was also rushed to hospital for emergency surgery in what Ronan described as the “scariest experience of my life” .
He said at the time: ”Well that was a week I never want to live again. To have my Storm in hospital under the most extreme circumstances and not be able to see her and hold her hand and give her a hug and tell her everything was going to be ok was the toughest I have known. I felt so helpless, her strength is insane.”
Jack's family will now be running his social media while he is in the Love Island villa.
Posting on his Instagram, they wrote: "Officially entering the villa of love #casaamor. Your new favourite Irish lad Jackoooo, will be on your screens @9pm tonight @loveisland @itv2
"The Keating clan reporting for duty to give you your live updates & best bits of our boyo. Ahhhhh so excited for this."
Jack said his family and friends would describe him as a "lively guy" He said: "I'm a great crack to be around, always up for a chat, always up for a bit of banter."
He has been single for around four or five years and hopes to find a connection with one of the girls. He said: "I’ve really been missing that spark that I haven’t been getting on the dating scene."
The contestant has admitted to not having any "icks" but is looking for a girl who is family orientated.
Jack isn't the only offspring of a celebrity, with Gemma Owen - the daughter of Michael Owen - entering the villa on day one.
