Nick explained,"I have a good friend, Demi Lovato, and we write songs together and that was like our goals. 'Let's find ways to slide these references in and only the person listening will know.'"
We've got to guess there's a reference in one of his songs to Delta Goodrem, who he recently said he still keeps in touch with, telling news.com.au: "We run in different circles these days. But from time to time we talk."
Nick added, "I think that life is about a journey and growth - and each person that's a part of your life is meaningful and important. And I think that there is always love there. It's a part of the journey. I can say now that I'm thankful to have had all the experiences - and that was an important chapter of my life - but I'm thrilled to be in a new chapter."
