Sources on the "Las Vegas" set claim that while Duhamel prepared to film a scene, he overheard one extra saying to another that he would like to "*@#$" Fergie. Chivalrous Duhamel immediately approached the extra and yelled, "What did you say?" Before the extra had a chance to respond, Josh had pushed him so hard that he slammed into another extra.
The extra wasn't about to back down and pushed Josh back. Josh was about to slug the extra when crewmembers called for security and moved the two men apart. The extra was asked to leave the show and Josh continued on with the scene.
