Last we heard from Green Day, it was frontman Billie Joe Armstrong saying the next project he does would be a new album for his main band! BUT, was that album already completed, and was it produced by Butch Walker?? There's an interesting theory out there trying to prove that it's the case!

Notable Green Day source greendayonline.net seems to think a new Green Day album is coming soon and has been secretly produced by the multi-talented Butch Walker. Butch is known for working with Panic! At The Disco, Weezer, Fall Out Boy, The Struts, and a ton more!

So where are people getting these ideas?? WELL....for one there's this random Instagram account @songsfora**holes (without the stars hah) that only members of Green day (as well as their family and close friends) followed. The account us private but it's said that in March it was posted to daily. It's said that's when the band was working on the album. So where does Butch come in? Well, he's also a follower of this mysterious account. The other followers are only people within Green Day's inner circle so it seems that Butch would be "working" with the band.

There's also the fact that Butch posted a video to his Instagram showing him in a recording studio where he said he was "making records," and in the background it looks like Green Day drummer Tre Cool's drum kit is there with him. Tre and his wife both liked the video.

Billie Joe's wife also posted a picture to her Instagram with BJA and Butch featured in it too!

So did Green Day already finish an album without us knowing (until now)? I guess we'll have to wait and see!
