He wrote: ‘Jack Conrad Fox. 8th June 2025. Five weeks early.

‘Oh he’s tiny. Congratulations to you all!’;

‘Congratulations good date to be born on he will be a warrior.’;

‘Amazing!- nothing better. Feels surreal doesn’t it?! Enjoy your #babymoon.’ 

The TV star took to Instagram earlier this year to announce his impending arrival.

Alongside a picture of the baby’s ultrasound, he wrote: ‘As good a time as any to say that this time next year there’ll be a new sheriff (mum) in town for Mother’s Day!

‘So proud of you @julesfoxter in how you’ve approached and taken on this long journey…’

Jason, who is the longest-serving cast member on SAS: Who Dares Wins, has candidly spoken about his life in the spotlight after developing PTSD following two decades in the army.

But despite his own struggles, Jason told the Metro that he would be ‘fully behind’ his children if they chose to join the military but said that he would advise them to ‘think long and hard’ about joining. 

Explaining how he got into TV, he said: ‘I found myself in serious financial schtuck with no job and medically discharged with PTSD, which didn’t lend itself very well to the jobs that would have suited me.

‘Then a mate gave me a job looking after a TV crew. It went well and my name came up when they were discussing SAS: Who Dares Wins.’

Jason has since built an incredibly successful career on the show and become known as a no-nonsense coach on the quasi-military training Channel 4 program.
