Veteran entertainer Bette Midler has urged young pop stars like Britney Spears, Miley Cyrus and Lady Gaga to show some class as they continue to test the boundaries of sexiness and creativity, because they risk demeaning all women with their "gross" stunts. The singer/actress is not naming names, but she admits some of the revealing and eye-popping performances she has seen of late have done little for womenkind and she appears to refer to Spears' latest video for Work B**ch!, in which the singer grinds in a bikini before cracking a whip at one female crawling on the floor, as one of the more crass acts she does not approve of. Midler tells U.S. talk show host Katie Couric, "I think there's a difference between pushing the envelope sexually and pushing the envelope creatively. I think you can be as creative as you want to be and as inventive as you want to be... but I think the idea of whipping other girls... I don't know. There's a grossness to it that I think is not flattering to people, to the women themselves. "Not all the time, I'm not saying all the time because some people are very sensitive about the way they use their bodies and the way they use their sexual power. But I do think that when it's really gross, when it's really coarse, it's so demeaning, not just to them but to all women and I don't really like it. I don't like it." Midler isn't the only star speaking out - Katy Perry has also urged her fellow pop peers to focus on their talents and halt the trend of stripping off onstage and in videos. She said, "I'm not talking about anyone in particular. I'm talking about all of them. I mean, it's like everybody's so naked. It's like, 'Put it away. We know you've got it. I got it, too'. "I've taken it out here and there. And I'm not necessarily judging. I'm just saying sometimes it's nice to play that card, but also it's nice to play other cards. And I know I have that sexy card in my deck, but I don't always have to use that card."
