MISTRIAL! After extended jury deliberations that lasted twice as long as the trial itself, the Britney Spears License Trial of the Century ended this afternoon in a mistrial. Attorneys gave their closing arguments another try this morning, not long after the jury foreman acknowledged the panel was split 10-2 (he wouldn't disclose which way) as to whether or not Spears broke the law last summer while driving, hitting and running without a California license. The singer avoids potential jail time at a critical juncture in her career, thus clearing her name (for now), restoring her newfound momentum and reopening herself to another decade at least of catty Mr. Blackwell rejoinders from beyond the grave. Congrats, Brit! [AP ]
