Britney Spears couldn’t even score 50% on her drug tests….I mean she couldn’t even show up for 50% of her drug tests. Spears missed 8 out of 14 drug tests according to Kevin Federline’s attorney.

Alleging the singer lives in a “parallel universe,” lawyer Mark Vincent Kaplan reminded the court that the singer had been reprimanded three times by Commissioner Scott Gordon for failing to be reachable by phone.

“Mr. Federline doesn’t want to take these children out of their mother’s life, but what are we to do?” Kaplan said.

Spears’s lawyer, Anne Kiley, called the current drug testing procedure “unconstitutional,” adding that just because the singer may fail to respond to testing calls doesn’t mean she’s using drugs. Kiley also pointed out that Spears has passed multiple tests successfully.

Britney’s attorney continues to show that she is squarely outmatched by Federline’s barrister.
