KUALA LUMPUR: Bootylicious R&B singer, Beyonce Knowles, has been asked to cover up during her debut concert here in November.Pineapple Concerts chairman Razlan Ahmad Razali, who is the organiser of the show, said her performance would still go on as planned, but her dressing would have to be toned down and there would be less exposure of her body."As of now, her concert is still on, " he said, when contacted yesterday.Beyonce, 25, from Houston, Texas, is not only famous for her powerful vocals but also her revealing costumes.The Grammy Award winner, who has achieved superstardom with well-acclaimed solo albums like Dangerously in Love and B’day, is not the first foreign artiste who has been told to abide by Malaysia’s dress code.Last month, Gwen Stefani had to endure a storm of criticism from various religious groups who called on the government to cancel her concert due to her "overly exposed dressing" which they claimed was too "sexy" and was inappropriate for the Malaysian audience.Malaysia received a lot of negative publicity from the foreign media which sees Stefani as a role model.Amid the controversy, Stefani went ahead with "The Sweet Escape Concert 2007" on Aug 21. Although she was dressed decently, the show was still a tremendous success with a sell-out audience.
