LATEST: Killers singer Brandon Flowers has apologised to rival bands he has bad-mouthed and vows to keep his mouth shut for now on. The American rocker landed in trouble after attacking the 'Emo' pop punk movement, and warning it will sweep the nation and change the teenage generation forever. Bands he targetted, including PANIC! AT THE DISCO and Fall Out Boy, reacted angrily and Flowers accepts he was wrong to speak out. He says, "I'd like to take it all back. These people are just doing what they want to do, just like I am. "I'm actually a nice person and I love people. I just am opinionated, and sometimes jealous. It's not something I'm proud of." Flowers is particularly remorseful to have targetted Panic! At The Disco - because he has never heard their music. He adds, "I don't even know what their music's like, or if I would even like it. That made me feel even worse, to think they could have been fans of ours and I hurt their feelings. That's just stupid."
