The 'Suicide Squad' actor admits he has struggled to be in a relationship for the last few years after a former partner tragically passed away in a road traffic accident.
He recalled: "I dated a girl a couple of years ago who died in a car accident. The f***ed up thing is, it was a fender bender, and there was a recall on airbags. Her airbag exploded. It shot a projectile through her body. It split her spine, and ... I've never told anybody that.
"I've lost friends before; I've lost some great friends. But, I had never lost someone I had been really intimate with. Maybe it's made it harder for me to date."
And the 30-year-old actor admits he now understands how fleeting love can be.
He added to Australia's GQ magazine: "It's easy to fall in love when you're young, right?
"And then you start to realise those feelings of love and stuff, passion, love, lust, sometimes they come very quickly, but they can also leave quickly."
Meanwhile, Scott previously admitted he would give up his acting career for 'The One'.
Asked if he'd give up his job for the love of his life, he said: "Yes I would. I think that's the ultimate sacrifice and if I couldn't see my life without her then of course. She would have to be 'The One' though."
And Scott wouldn't hesitate to let his father Clint set him up with someone.
He shared: "When I was 16 he was rooting for me and this older girl. He wanted me to make it happen and it did. He was so happy. Would I trust him to pick me a girl? Yes sure. I absolutely would."
