Why He's Hot: Luis Coronel hadn't even finished high school before he was trending on social media and showing up on the Billboard charts in 2013. One year later, the regional Mexican singer with a major teen following in the U.S. and beyond has a thriving career under his belt. The Del Records artist spent three weeks at No. 1 on the Regional Mexican Albums chart with Con La Frente En Alto in October 2013 and his single "Tenerte" spent three weeks at No. 1 on the Regional Mexican Airplay charts earlier this year. He's also had two top 10 hits on Hot Latin Songs, has won trophies for new artist of the year at the 2014 Billboard Latin Music Awards and social media sensation on Telemundo's Premios Tu Mundo awards show, has served as a judge on the Mexican singing competition show La Academia Kids and has toured with major recording acts Julion Alvarez to Gerardo Ortiz. Next up for Coronel: a new album, Quiero Ser Tu Dueno, due on Sept. 30.
