The 22-year-old singer is on the verge of a mega-breakthrough these days, but she’s been building up to it for more than a decade. She first started turning heads with appearances on ‘Star Search,’ ‘America’s Most Talented Kids,’ and ‘American Idol.’ Then she hit YouTube, where she earned herself more than a million followers by covering Paramore and Justin Timberlake. In 2012, she continued the DIY approach with an EP she wrote and recorded in her California bedroom.
