Killers singer Brandon Flowers says his days of making outlandish statements to the press about his band are over. Talking to MTV News, Flowers said, "It's easier on the band, [and] it's so much nicer to put positive things out there, positive vibrations I just found myself regretting it ... I still carry it with me; I'll be brushing my teeth and I'll think 'God, I wish I wouldn't have said that about whoever I said anything about.' And then I'm trying to get my manager to get their phone numbers and sh--, so I can tell them I'm sorry. So I learned a big lesson, and now, I do kind of the opposite. If I hear something I like, I try to get in touch with these people and tell them I like it. It's a lot more rewarding." The Killers' new album Battle Born is due out September 18.
