Grace wrote her very first song at just 11 years old while procrastinating doing her homework. Little did she know that a mere few years later she'd be on tour, drawing out fans from all over the world.

While getting her makeup done for a music video shoot for "City Song," Grace says, "I feel like personally, this has been the worst year of my life. And then career wise, this has been the best year of my life."

And in case you were wondering about how she balances school with her new career, she explains, "I once had to finish the 7th grade in one night. Before the deadline." She took all of her tests and finals in three days.

Grace's dad says, "She's taken on so much. I don't think there are many 13-year-olds that could do it."
