Outspoken rocker Noel Gallagher has lashed out at Miley Cyrus and Lady Gaga, insisting their antics outside the recording studio have set the world's most talented female singers back five years. The former Oasis star admits he's not a fan of provocative performers who bare all onstage and in videos, and he has targeted Cyrus and Gaga specifically, urging them to concentrate on making great music without all the fanfare and drama. He tells RollingStone.com, "I think there's a trend, unfortunately, in the game, at the minute, of girls desperately trying to be provocative or desperately trying to... 'start the debate' about some old s**t or other. Because, really, they're not very good. "We have it in England regularly, and you have it in the States. I feel bad for 'em. It's like, 'Write a good song. Don't make a provocative video. Write a good f**king song, that'll serve you better, I think'. "She was on TV recently, Miley Ray Cyrus, and it was just like, 'What the f**k is all this about?' I don't know. It's a shame, because it puts all the other female artists back about f**king five years. Now, Adele and Emeli Sande - that music, to me, is like music for f**king grannies (grandmothers), but at least it's got some kind of credibility. "Be good. Don't be outrageous. Anybody can be outrageous! I could go to the Rolling Stone office and f**king s**t on top of a boiled egg, right? And people would go, 'Wow, f**king hell, that's outrageous!' But is it any good? No, because, essentially, it's just a s**t on top of a boiled egg. That's all it is. If I was to go to your office and play you a song that I'd just written that was amazing, that would be better, wouldn't it? I feel bad for the girls. The sisters are not doing it for themselves." And turning on Lady Gaga, he adds, "Lady Gaga, for me, is all about that first album, because my daughter and my wife loved it. I've never heard of her since. What does that say? That speaks volumes to me. She's another one. In fact, she's probably doing a s**t on top of a boiled egg right now. And somebody will f**king freeze it and call it art."
