Britney Spears memorabilia has never been more in demand, according to auction website eBay - the troubled pop star sold more than 34,000 related items online in 2007. That compares with 27,377 items associated with Paris Hilton. Items associated with Spears ranged from signed CDs to disposable lighters featuring her likeness, according to U.S. news show Access Hollywood. Among the Hilton-related items sold was a toothbrush reportedly found in the hotel heiress' trash. But neither Hilton nor Spears could match baseball superstar Barry Bonds - more than 145,000 items related to him, including a grilled-cheese sandwich, sold on eBay.
