Gov. Chris Christie delivered an expletive-filled speech on Wednesday night at a dinner in New Jersey in a room full of reporters, lobbyists and political insiders. Organizers said the speech was off the record, meaning the reporters inside the event agreed not to write about his remarks; some attendees said the ground rules were unclear.

International Business Times obtained an audio recording of Christie's remarks. IBTimes was not at the event and was given the recording by an attendee.

Christie's office did not contest the authenticity of the recording. Kevin Roberts, Christie's spokesman, issued a statement in response to inquiries about the speech.

“All of the songs and acts of the night, including the governor’s obvious parody of himself, were in jest and along with the spirit of the evening," Roberts said. "This is in keeping with what the dinner is about -- bringing people together off-the-clock for a night of comedy and self-deprecation in support of the Press Foundation’s scholarship programs. That anyone would misrepresent the traditional lighthearted nature of the event is a disservice to everyone involved.”
