Music producer Mark Ronson is hoping pal Amy Winehouse attends the Grammys in Los Angeles on Sunday (10Feb08) - because the event will be "boring without her". Winehouse is currently seeking permission to enter the U.S. to attend the star-studded Los Angeles ceremony, where she is nominated for six awards. But the singer's alleged drug taking could scupper her chances of being granted a visa, after she was filmed allegedly smoking crack cocaine in footage obtained by a British tabloid newspaper. And Ronson - who collaborated with Winehouse on her sophomore album Back To Black - insist the Grammys will be lacking in fun if the 24-year-old is unable to attend. He says, "I hope Amy can make it. It'll be boring without her." Winehouse was banned from the U.S. last October (07) after she was arrested and fined in Norway for possession of cannabis.
