Sting and Trudie were guests at the sixth 'White Tie and Tiara Ball' hosted by Elton John at his home in Windsor on June 25. This year's theme was Imperial China. The musical entertainment was provided by Elton and his band, along with special guests Bryan Adams and Mary J. Blige. Bryan Adams played an acoustic set and was followed onstage by Mary J. Blige who sang solo first and then duetted with Elton. Elton and the band played together and were then rejoined onstage by Bryan Adams. Elton's official website reported that other celebrity guests included Rod Stewart and Penny Lancaster, Kylie Minogue, Ozzy and Sharon Osbourne, Liz Hurley, Sir Ian McKellan, Dame Shirley Bassey, Elle Macpherson, and Sir Michael Caine. The auction items included a brand new Aston Martin DB9 (for which Rod Stewart bid £450,000!), a portrait session with photographer Patrick Demarchelier, an Audi TT Roadster 150bhp, and a trip for two to Hong Kong and Beijing, including a private tour of the Great Wall of China, the Forbidden City and the Temple of Heavenly Peace. But the ultimate Elton auction item must be the trip for two on Virgin Atlantic to Las Vegas to see Elton's The Red Piano concert, and to have dinner after the show with Elton and David in their Caesars Palace suite!
