LOVE Island fans were stunned when new arrival Jack Keating announced his age – insisting he looked much younger.

The Irish lad is another of this year’s celebrity offspring as the eldest son of ex-Boyzone legend Ronan.

But many were shocked that he is 23 with many reckoning the baby-faced lad looked more like a teenager.

一个开玩笑的: “Ain’t no way jack is 23 he look fresh out of yr8.”

另一个同意: “Jack does not look 23” while another tweeted: “Plz is Jack of legal age to be on this show??”

The lad introduced himself on 爱情岛 last night saying: “I’m Jack, 我是 23 and I’m from Dublin and I work in social media and marketing.

“I’ve been on the dating scene for a while. I do most of my chatting up on Instagram to be honest with you.

“The swipe up, love heart on someone’s story, that always goes down a treat.”

他加了: “I’m ready to go in there with my heart on my sleeve, get my graft on, get my pulling boots on. I do hope they love a bit of Irish charm.”

Talking about Ronan, 45, before going into the villa Jack explained: “He will be watching when I’m on it for sure.

“He’s buzzing for me, me and my dad are very close, we’re best mates.”

Jack is joined in Casa Amor by accounts manager Deji Adeniyi, 25, labourer George Tasker, 23, models Josh Samuel Le Grove, 22 and Samuel Agbiji, and roofer Billy Brown, 23.

Love Island viewers last night saw them bounding into the villa, with Jack leading the charge, as the girls sat by the pool open-mouthed.

The lad, who lives in London and works in social media marketing, is the only son from Ronan’s first marriage to wife Yvonne alongside sisters Missy and Ali.

他们分道扬镳 2015 and the singer went on to have two children called Cooper and Coco with second wife Storm.
