Possible Megan Fox Threat

Apparently this is from the backstage scenes of one of Megan's Transformers films. It would have to be either T1 or T2; I can confirm it isn't from Ninja Turtles. But HOLY SHIT would I like the video to this. I've seen the screenshot of this with the subtitles mentioning the spanking threat too, but the gif seems hopelessly short. Hope someone here can do what people here do best!
