"I think, know that everything that everything is happening for the right reason. I knew that when we weren't together the first time. I didn't know if that was the end of it or knew if we'd be back together again, but knew that wherever I was going was on the right path.
The 24-year-old singer also opened up about her sobriety and the positive impact quitting grass on her career.
"I've got a lot of energy. I've always had a lot of energy," she said. "I'm a very obsessive person, which I need to work on, but also it helps in my position to be a little obsessive because then I can really get things done and make sure it's perfect the way I want things to look or the video," she says.
