Jordan's dad, Graham North, was stationed in Omagh, Northern Ireland, in the 90s, and the family was due to go into the town centre on August 15, 1998.
That same day, the IRA detonated a bomb that killed 29 people, including a woman who was tragically pregnant with twins at the time.
The terror attack, which saw a car bomb explode on Banbridge High Street, rocked both Ireland and the UK, and is remembered as the worst terror attack in Northern Ireland's history.
Jordan, 30, previously revealed he was supposed to head into town that summer's day, but his mum decided against the trip.
Aged eight at the time, Jordan recalled: "My dad was in the Army for 24 years. In 1997 his battalion, the Queen's Lancashire Regiment, was posted to Omagh so we moved out there.
"In August 1998, when the Omagh bomb happened, we were there at the time and we were meant to be going into town that day, into Omagh.
"But I'm one of four boys and my mum said we were all playing up. It was in the middle of the summer holidays and it was hot. It wasn't raining for once.
"But my mum said, ‘I'm not going into town with these lot. They're doing my head in', so we decided to go for a walk."
According to The Mirror, Jordan opened up about the experience during an interview on the show Lockdown Lowdown, on BBC Radio Ulster, which was recorded months before he took part in I'm A Celeb.
The Radio 1 DJ remembered the moment the bomb went off, saying: "We were in Gortin Glen when the bomb went off.
"We heard it from there. It was an awful time. Dad rushed us all into the car because he knew we had to be back on camp.
"I remember I was only eight years old and it was one of the first times I felt really sad."
Jordan's elder brother, Sgt Ryan North, followed in their father's footsteps and joined the army, serving in the 2nd Battalion, Parachute Regiment.
The 34-year-old war hero was given a bravery award for rescuing his colleagues during a firefight with the Taliban in Afghanistan.
Sgt North is proud of his little brother, with the family rooting for the radio presenter as he battles to be crowned King of the Castle.
Tonight will see Jordan face Giovanna Fletcher and Vernon Kay in the finale, as three weeks of I'm A Celeb draw to a close.
I'm A Celebrity continues tonight at 9pm on ITV.
