Kevin Federline is once again dragging Britney Spears back into court for an emergency custody hearing, Usmagazine.com has learned. The session will take place on Friday in L.A. Superior Court.

Spears attorney Anne Kiley confirms to Us that Federline’s lawyer, Mark Vincent Kaplan, has requested a hearing to address Spears’ running of a red light with her two kids in the back seat on Nov. 8 (a court-appointed monitor was also in the car).

The couple’s most recent court appearance came last Thursday, when it was revealed that Spears failed to take eight of 14 random drug and alcohol tests. At the hearing, Court commissioner Scott Gordon ordered Spears to get a single, working telephone number where she could be called for future tests.
