Madison Beer is not primarily known as an author but rather an American singer and songwriter. Born on March 5, 1999, in Jericho, New York, she gained attention after pop star Justin Bieber shared one of her singing videos from YouTube, leading her to secure a recording deal. Beer's music career began with her debut single "Melodies" in 2013, and she has since released a series of singles and her debut studio album, "Life Support," in 2021. Her music blends pop with R&B influences, and she is also known for her strong social media presence. If Madison Beer has ventured into writing or released any books, that information wasn't widely recognized as of my last update, and she is best known for her contributions to the music industry.
