It seems as though there is more trouble brewing for Britney Spears.  TMZ.blog is reporting that the fallen pop star has failed one of those court ordered drug and alcohol tests.

This is definitely bad timing for Spears as her ex-hubby Kevin Federline will be back in court this week to prove that she is not a good mother.

Federline's attorney is headed back into court this week to try and ban Spears from driving with her kids in the car.

TMZ also reported last week that Britney was spotted breezing through a red light with her kids and a court appointed monitor in the car.

As for the alleged failed drug test, Britney's friends tell TMZ it was a false positive.

Can drug tests have false positives?  I guess the truth will come out in court!
