"Sometimes you feel awkward being what you're best at, you feel like you have to be something new. But I think that a lot of people will agree that me being me at my best is what I need to be.
"I think that has really paid off because I'm back with Evan."
The 'Disposable Teens' singer - real name Brian Warner - believes the relationship will have an impact on his future songwriting.
Asked about the direction his music will take, he told Metal Hammer magazine: "I think it will be more bada*s , I think it's going to be more romantic, maybe. Self abusive."
