Brian Justin Crum ended his fantastic run on America's Got Talent last night with an absolutely epic performance of Michael Jackson's "Man In the Mirror."

The 28-year-old powerhouse has consistently impressed both the judges and the audience each week since his audition, when he opened up about being bullied when he was younger and moving to Los Angeles to pursue his dreams as a singer.

Crum delivered his haunting cover of the King of Pop in a sparkling suit jacket, standing on an elevated stage beneath an intense pyrotechnic finale.

Everyone including Simon Cowell, the juding panel's toughest critic, agreed that the performance was one of a lifetime.

"I thought when the song first started ‘you just made a huge mistake here’ and then halfway through I thought ‘actually, you know what, you’ve just made the best decision of your life with that song,'" said Cowell. "I really do. I thought it was really, really incredible. And you know something Brian, there is a big difference between people who come on every week and just sing and are forgotten. With you, you are just a naturally brilliant performer."

Before his performance, Crum wrote on Facebook: "Im dedicating this performance to anyone who ever felt like they werent enough. You are so loved. Thank you for your continued support and know that ill be thinking of you all while I sing tonight. Be strong and be YOU!"

On Wednesday night's show, Crum will find out if he's the winner of the popular vote and a $1 million prize.
