Hollywood beauty Mischa Barton reportedly offended British royal LORD FREDDIE WINDSOR by playing with her Blackberry personal organiser throughout a dinner party at London's Kensington Palace. The 27-year-old offspring of Princess Michael Of Kent invited the former The OC star to dine at his parent's residence in the British capital and was stunned when she brought along her hairdresser pal ANDY LeCOMPTE. A source tells British newspaper Daily Mail, "She brought along her hairdresser as chaperone. Even though Mischa was seated right next to Freddie, she spent the whole meal tapping text messages into her Blackberry. "Freddie was rather offended."
