Billie has recently said in an interview that he is agnostic.

His quote. - "[on if he believes in heaven] I consider myself an agnostic, so I'm not really sure. I kind of believe that there's something possibly out there. I'm not stubborn enough to cancel that out. I believe there's a higher power somewhere. I just don't know what it is."
