Britney Spears' Positive Drug Test Sparks Controversy

A source connected to Britney Spears says she tested positive in one of her recent drug exams, although the source says it was a false positive.

"The only thing that comes on the results are the prescriptions, that the court doctor prescribed," the source close to Spears added, "There has been no illegal drugs or even alcohol in any of the test results."

Britney Spears is seeing a psychiatrist as part of her ongoing custody case. That could be what the source was talking about with respect to the court doctor.

There are reports that Britney's positive drug test last week was due to Provigil, a prescription for treatment of narcolepsy. It turns out this is not the case.

In generic drug testing ordered by the courts - the type performed on Britney Spears - there is not a special screening used to detect Provigil.

The tests actually performed on Britney Spears (at least until last week) all came back negative, and she had been taking Provigil before that. Strange.

Meanwhile, Kevin Federline's lawyer, Mark Vincent Kaplan, has contacted TMZ to notify the celebrity news site that he will subpoena a story it posted late last week about Britney running a red light in her Mercedes.

Mark Vincent Kaplan wants the tape for a court appearance Wednesday.

The story, which ran Friday on TMZ, shows Britney - her kids in the back and the court-appointed monitor ducking in horror in the front - blowing through a red light at an extremely dangerous intersection on Thursday night.

A close look at Britney Spears photos from that incident shows her holding a phone up to her face seconds before running the light - as if sending a text message.
