Jeez, those Britney Spears lawyers must be exhausted! Britney and Kevin Federline's lawyers are scheduled to return to court this morning, for an emergency hearing in the never-ending custody battle for their boys. Sources say that the hearing was called by Kevin's attorney, Mark Vincent Kaplan, who's alleging that Brit has, yet again, failed to follow drug-testing procedures. Apparently, if Britney hasn't been doing what she's supposed to, regarding the drug-testing, the court could suspend all of her visitation rights -- again. Maybe she is crazy. I mean, could someone actually be this thick?
