Posted January 31, 200817 yr Mary J. Blige has defended Amy Winehouse against claims that she is setting a bad example to fans with her drug use. The R'n'B star, who has beaten addictions to drugs and alcohol in the past, said Winehouse was a "perfect example" and should not be criticised for her lifestyle. WENN quotes her as saying: "Amy's music means something. If you look at the truth, leadership and honesty in music, Amy is the perfect example. "She's probably the best thing in the business now. I hope I can collaborate with her." Winehouse checked into a rehab clinic in London last week. digitalspy
