Before he became a chart-topping singer, this celebrity was just a kid in cowboy gear in San Antonio, Texas.
Back in 2010, he posted a YouTube cover of Justin Bieber's "Mistletoe" while rocking his Western look.
That early clip has since given way to a full-fledged music career.
He has collaborated with major stars, including Pitbull on the track "Mmm Yeah!"
Today, he boasts more than 11 million followers on Instagram.
Can you guess who he is?
