Poor old Whitney Houston. It's been a really rough week for her. Things started badly on Tuesday when she had to postpone the opening of the European leg of her World Tour due to an upper respiratory infection. Naturally, the French fans were disappointed but things were looking better for the UK with the tour scheduled to start in Manchester on Thursday. However, these dates in Manchester and Glasgow have also been postponed so more fans here will have to wait until May and June to see her. To make matters worse, there have then been allegations of drugs use, which according to Whitney are "ridiculous". We hope she gets better soon as she has such a great voice and is so very talented. In fact, she's just arrived in the UK and says she feels great! Here are the remaining tour dates for UK fans:

According to people.com, the lovely Country singer Shania Twain has been lined up to take Paula Abdul's place on the American Idol judging team in Chicago on August 30/31. It should be good news for Shania fans who haven't seen her for a while - she hasn't released any new material since 1992 when Up! was released as a double album, with three different discs—pop (a red CD), country (a green CD), and Indian film music (a blue CD). However, her record company recently denied that any new releases were imminent, so the appearance on American Idol might be all fans can hope for this year.
