“I wrote the best music once my heart was broken,” Justin recently told Power 106 (via E! Online). “‘All That Matters’ was written when I was in a great place in my relationship, and at that time, [Selena Gomez] was all that mattered in my life. [The break up] affected us, especially when we are in front of so many people. It’s such a public thing. It’s just hard for the both of us. But you know, she’s a great woman. I love her till this day.”

Justin added, “I think we’re going to be the greatest of friends. Right now we’re taking a little time and not talking.”
