British pop star Jamelia is jealous of chart rival Amy Winehouse's success and critical acclaim. Winehouse has quickly overtaken Jamelia as the U.K.'s number one female solo artist, and the R+B star confesses she'd love to trade places. Jamelia says, "Of course I'd love that acclaim. I think any artist would love to have what Amy has and to gain that kind of respect. "I like her, she has a good album. Although I'm sure all the hype surrounding her helps. I hope she gets well soon - it's a shame. But her music speaks for itself." Winehouse recently underwent a brief spell in rehab following allegations of drug and alcohol addiction.
