'It was great to be able to collaborate with him,' she says of Smashing Pumpkins frontman.

"Billy is a dear friend of mine and I asked him to help out with arranging the song," she told MTV News. "And he had some ideas to change it up a bit musically and some really cool arrangements and some great guitar things."

Simpson explained that working with Corgan, who came to the singer's defense after John Mayer made explicit comments about her in a recent Playboy interview, really taught her a lot. "To be able to sit with Billy [is a learning experience], and I always feel comfortable with him 'cause he is a close friend of mine," she said. "And I know he had my best interest at heart and it was great to be able to collaborate with him and to have him there in the studio."

The song embraces the show's theme about loving the person you are. "I ended up writing the song with some friends and it was about all these places that I'd gone to and the experience that I had," she said. "It's about the beauty of who we are and embracing that and knowing that we are all authentic — that every single person is different," she added. "But they all have something different about themselves that they need to discover."
