Duran Duran frontman Simon Le Bon fears troubled star Amy Winehouse is ruining her career with her high-profile drug use. The Rio singer, who himself is no stranger to the dangers of rock n' roll excess, is worried Winehouse is jeopardising her full career potential after suffering a drugs overdose in August (07). Le Bon says, "Any kind of drug conviction can get you banned from America and Amy has the potential to be massive over there. "This is her time, her moment, and I'd hate to see her waste it." Winehouse was also recently (18Oct07) arrested in Norway for marijuana possession, but was later released with a 500 euro ($696/GBP348) fine.
