Hey, some stuff happened that doesn’t have to do with the Emmy Awards. For starters, Billie Joe Armstrong of Green Day is reportedly heading to rehab on the heels of a profanity-filled tirade at the iHeartRadio Festival over the weekend in which he reminded us all that he is “not [expletive] Justin Bieber.” The rant occurred after Usher’s performance carved out 20 minutes of Green Day’s stage time and Armstrong flipped out when he was warned that the band had just one minute left to perform. Armstrong later issued an apology. He is seeking treatment for unspecified substance abuse. Green Day also has canceled all upcoming promotional appearances even though their new CD, “¡Uno!,” releases Tuesday. (Associated Press)

Speaking of stage tirades, Fiona Apple had some fascinating things to say about her recent pot possession arrest during a Friday night gig in Houston. “Most of the people were very nice to me,” she said of her experience with the Hudspeth County jail in Texas. “There are four of you out there . . . and I want you to know I heard everything you did . . . I wrote it all down with your names and everything you did and said, stupidly thinking that I couldn’t hear or see you. I then ripped the paper up, but not before I encoded it and — I got two lock boxes. We’ll call them ‘holding cell one’ and ‘holding cell two.’ In ‘holding cell one’ is the encoded version of the [expletive] that you did that I know was inappropriate and probably illegal. In ‘holding cell two’ is the decoder. I’m the only one who holds the key, and you and I will be intimate forever because I will hold that secret forever.” This quote, coincidentally, is also the title of Fiona Apple’s next CD.
