Britney pal and mystery man "Sam" has spoken to X17 exclusively to tell us a strange story of entrapment and assualt by five men he believes to be on the payroll of Kevin Federline's attorney, Mark Vincent Kaplan.

Sam claims Kevin's lawyer wants to subpoena him to testify in the custody battle waging between the former couple. He says a team of process servers, including one he believes to be the former Israeli militia man Aaron Cohen (who served Alli Sims just weeks ago), blocked his entrance to the parking garage at his apartment today as he returned him, surprising him with three cars driven into the path of his car, forcing an accident that left thousands of dollars of damage done to his new Mercedes.
