The 24-year-old singer dated the Norwegian record producer on and off from 2015 to 2016. "When we met, I was nobody; things changed very quickly," she said in a 2015 Billboard interview following their split. "A lot of people in my life freaked out. I didn't have the chance to say, 'I'm sorry, let me explain.' It was kind of like, 'If you can't keep up, f*ck you. I have to keep going.'"
