The 16-year-old singer actually performed and premiered her new single “Out Loud” at the pre-show.
Afterwards, Madison had a special message for her fans on Twitter who tuned in: “The fact that some of you guys have been with me from when I posted my first YouTube video and now THIS!?!?!!! INSANE. I LOVE YOU SO MUCH.”
FYI: Madison wore a limited edition Alexander McQueen dress with Alexander McQueen heels.
