The duo fell in love while filming the action movie in Namibian desert, reported Ace Showbiz.
"I saw Dayna straight away - she was the only girl from New Zealand and she stood out like a sore thumb," Dane recalled their first meeting.
"I saw her bag with her name on it and my opening line was literally: 'Hi. I see you're Dayna. I'm Dane.' That was about it."
Dane, a South African, and Dayne started to get to know each other while training and filming a fight scene between Hardy's Max and Theron's Furiosa.
