Moore skyrocketed to fame with her 1999 bubblegum pop hit "Candy," then went on to release a total of six albums. She also famously starred in 2002's gooey teen romance A Walk to Remember alongside Shane West.

"Finding these journals with so many bits and pieces of lyrics in them has made my heart sing," Moore wrote.
