We've learned that K-Fed is going back to court tomorrow, arguing that Brit is violating the Commissioner's drug testing order.
Sources say K-Fed's lawyer, Mark Vincent Kaplan, will go before L.A. County Commissioner Scott Gordon tomorrow morning, arguing that Britney has failed to respond in a timely manner when she is called for random drug testing. We're told Kaplan will ask to modify the existing custody order, giving Britney limited visitation rights.
We're told neither Britney nor K-Fed will be present. And, we're told, this could be a real dogfight.
