WHO: Our Next Up Artist of the Week is Madison Beer!

WHY: Madison Beer began her career by posting cover videos on YouTube which caught the attention of Justin Bieber. She was 13 years old when Justin re-tweeted her cover of "At Last" by Etta James and that got her signed to Island Records. Now, Madison is a huge social media star with over 9 million followers on Instagram and new music coming our way. The 18-year-old is not stopping any time soon and brought her talents to KIISFM's NextUp Stage to perform her new song "Dead."

FUN FACT: Madison has been on the cover of Vogue Italia and modeled for American Eagle's #WeAllCan campaign.

Madison also released her music video for "Dead" and if we're being honest, this video is fire. Take a look!
