We still don't know who Demi Lovato's "killer" duet partner is yet (though we have pretty good idea).

But now we know what the cover of her inspiring "Really Don't Care" single with Cher Lloyd looks like... and it's awesome.

“Whether its a break-up song or it’s just saying that you really don’t care what other people think, I think it’s an anthem for people,” Demi told On Air with Ryan Seacrest. “It’s something that everyone can relate to, whether you’ve been bullied or you’re going through a bad breakup.”
