Britney's drug-test meltdown

Ding-dang! Could things get ANY worse for Britney Spears? The de-throned Queen of Pop had a full-scale meltdown following a court-ordered drug test in Malibu yesterday. Britney burst into tears after visiting the clinic where the test was carried out, following a judge's ruling last week in her child custody case with Kevin Federline. And almost simultaneously, Brit was hit with the news that she'd be prosecuted for a hit-and-run incident on August 6, where she hit a parked Mercedes then left the scene without reporting the accident. Get this: She could face up to SIX MONTHS in jail for that! And there's more.. Apparently Britney has been driving all this time without a valid California Driving License. LA City Attorney spokesman Frank Mateljan said: "According to the DMV, Ms. Spears was never issued a California license – ever." Oops!
