Speaking to 9Now in August, the couple said it was important to have ‘each other’s backs’ at all times.

‘I can’t even imagine being in a situation where Jesse wouldn’t have my back, even if I was in the wrong,’ country singer Kirsty said.

‘But he’d always have my back and support me 100 per cent and the same with him as well.’

Jesse added that communication is also vital in a relationship, as well as ‘trust and honesty’.

The pair first started dating at the age of 16 and married in 2014.

‘We really are those lucky ones that found our soulmate. We don’t exist without each other really,’ Kirsty said.
