Bieber told Seacrest: “I wanted to make a Christmas album, because my fans haven’t heard my music in a long time. I wanted to do something that was charitable, but was also something that people haven’t heard before. Because there are a lot of Christmas songs on my album that are new and original that people haven’t heard.”
