Here's a Shakespearean case of mistaken identity with a 21st-century twist. Kate Middleton, a 29-year-old common woman from Kingsway, Northants, has been locked out of her Facebook account because she shares a name with Prince William's future wife. Facebook apparently believes the woman to be an impostor, and has banned her from the site. "I'm trying to arrange a 30th birthday party in February and now I can't get in touch with half the people," the non-royal Middleton said. "They should have got in touch with me first, asked me to contact them within a set period of time and prove who I was." Northants Middleton's boyfriend, Jonathan Ross, has been spared Facebook's wrath, despite the fact that he shares a name with a television presenter.
