Choreographer Laurie Ann Gibson — known for her role in teaching “Making The Band” contestants dance routines — has been fired from the popular reality series following an alleged altercation with the show’s executive producer Sean “Diddy” Combs.

The New York Daily News reports that the choreographer told authorities that a heated argument ensued between Combs and guest judge Michael Bivins over the performance of the latest group of band hopefuls last month, when she was restrained by Bivens and threatened with a chair by Diddy.

Gibson said she managed to break free from Biven’s grasp and left the venue in Greenwich Village, New York, shortly after. The incident allegedly took place on April 25 at the New York Sports Club, but she didn’t file a formal complaint until May 11.

Diddy has denied Gibson’s claims, calling her accusations an attempt to “take advantage” of his fame.

Diddy’s lawyer Benjamin Brafman told the New York Daily News, “This is just another example of a false accusation by someone trying to take advantage of Sean’s success and celebrity status.”

Gibson’s attorney Peter Toumbekis said her firing is a breach of contract.

The show’s finale has been delayed because of the dispute.
