We know what you’re thinking. How adult can a 19-year-old in the Adult Contemporary category be? Well, these days those kids have songwriters that help and the kind of voices that can convey emotion far beyond their years.

Two weeks before Shawn Mendes turns 20 years old, Billboard has announced that he has made history by having three of his songs hit the number one spot on the Adult Contemporary Chart — all before he has seen two decades on the planet.

He achieved this with his songs There's Nothing Holdin' Me Back as well as Stitches and even Treat You Better.

Taylor Swift came close to achieving this feat when Love Story and "You Belong With Me reached number one the year that Taylor turned 19. She didn’t have another number one on the chart until she was 20 years old.

Shawn’s three singles have also earned him pole position on the Adult Pop Songs chart. Clearly the perception of when one is an adult is getting lower and lower but that might not be a bad thing.
