The `Don`t Wanna Go Home` hitmaker insists he has simple tastes but admits he requests for his backstage dressing rooms to be infused with his favourite scents.
He said: "The only things I need on my rider are t-shirts, vests, fruit, veg, and vanilla-scentedcandles.
"I`m so simple! I`m super chilled, laid-back and can laugh at myself.
I`m all about enjoying life to the full and living in the moment."
Jason, 21, also admitted he was a target for bullies when he was younger because of his interest in performing, but he refused to give in to his tormentors.
He told Top of the Pops magazine: "I was prone to taunts when I was younger because I was into singing. But I`m a pretty big guy and when that stuff happened to me, I didn`t back down - I got into fights all the time.
"If you`re being bullied, you do have to put a stop to it straight away because if you do back down, it`s them winning and they`ll do it more. Stand up to it and it`ll go away because bullies don`t want to fight, they just want to show off."
