It's one of the hardest songs I've ever had to write, but I wrote it in hopes that you've gone through something similar in your life, and that it can fill in the BLANK for you like it did for me.

"I'm very excited to share my next album with you, especially this song because it's a great representation of what's to come. I've never put out a song like this before – it's very different for me, but I want to thank Taylor Swift for letting me know musically that I just couldn't keep this on my hard drive any longer. Thank you to all of my fans – you'll never know how much you mean to me…"

He had already teased: : "I think someone out there was giving me a sign that I needed to release it. So… I declare 'Hero' will be out everywhere on May 24th as the first single of my new album. Thank you for your support… you know who you are."

Charlie recently teamed up with K-Pop stars Stray Kids on 'Lose My Breath'.
