It is now clear that Green Day are not a fan of Justin Bieber. The punk rock band went all out when performing at Friday, September 21's iHeartRadio Music Festival, trashing a guitar and putting Bieber's name and profanity in the same sentence.
Frontman Billie Joe Armstrong was actually mad at the concert organizer for cutting short their set. He had the 1-minute warning sign from behind the arena while performing their hit "Basket Case". Venting his frustration, Armstrong started smashing his guitar mid-performance and said, "I'm going to play a f**king new song. F**k this sh*t. Gimme a f**king break. One minute left. One minute f**king left. You're going to give me one minute."
The rocker eventually left the stage, but that's after saying "I'm not f**king Justin Bieber, you motherf**kers. You've got to be f**king joking. I got one minute. One minute left. Now I got nothing left."
The concert festival held in Las Vegas was also presenting No Doubt and Lil Wayne but not Bieber. It continues on Saturday evening with the performances from Linkin Park, Pitbull and Taylor Swift among others.
