And if that isn't enough of a further boost to her already impressive rock credentials, the pop icon also reveals she'd quite like to join metalcore heroes Knocked Loose on a track.
She recently revealed plans to release REVAMPED, an album full of her career-defining songs with "a fresh perspective that reflects her current artistic vision" on September 15.
On her future plans to continue her rock career, she tells the Metal Ambassador Podcast: "Someone I've always wanted to work with is Corey Taylor and, you know, obviously working with bands like Knocked Loose would be sick, too.
"So I think it's something that's on my wish list but hopefully I'll have some collaborations for Revamped. We're still working that out, though."
Lovato also recalls how Job For A Cowboy's track Entombment of a Machine helped her fall in love with metal.
She adds: "It was the first song that I realised metal music, in a way, can be catchy without being a pop song because you listen for the guitar riffs, you listen for that certain part of the song. I just fell in love with it and that song is what did it for me."
Last month Lovato explained why she had gone back to using she/her pronouns, saying having to explain they/them to others was "absolutely exhausting".
