Singer Leona Lewis, the bookies' favorite to win popular British talent spotting show "The X Factor", has fallen victim to "celebrity cybersquatting", with an Internet domain bearing her name up for auction on eBay. The domain, www.leonalewis.net, is for sale on the electronic auctioneer's site and has received a top bid of 31 pounds ($60) so far, although experts say its value could rise sharply over the coming days.
