( Contactmusic ) - Singer SHERYL CROW has refuted claims she once vowed to use only one piece of toilet roll every time she visited the bathroom. The star insists her now infamous words during a promotional eco-awareness campaign in the U.S. last year (07) - were taken out of context to "embarrass" her. She says, "They took something that was part of a comic routine we were doing on the Global Warming college tour and set it up as if it was something that I believed in, to embarrass me. It was really embarrassing to watch. "It was on every news channel as if it was news. It was everywhere. That's when I want to shake people and say, 'You've got to wake up. You watch the news and you believe this stuff?'"
