Teigen, 27, posted the video to her Instagram account on Christmas Day, telling her fans "Merry Christmas" before Legend is shown choking her. The model, looking distressed, then asks for help as she and Legend, 34, pretend to fight on camera.
The video has since been removed. Teigen has yet to explain why she decided to delete the video.
Legend and Teigen, who have been together since 2007, married in September.
