The FEEL star was admitted to The Meadows rehabilitation clinic in Arizona last month (FEB07), and his sister SALLY is pleased with his progress. She tells their Stoke-On-Trent, England hometown newspaper The Sentinel, "Robbie is doing OK. He told mum he was concerned how it would be portrayed in the media. He was relieved it was all positive.
