Jessie J (born 27 March 1988) is an English singer and songwriter.
The 24-year-old singer is seen sitting on a chair singing as images from the flick are projected on to her naked body.
The raunchy footage of Jessie is pieced together with clips of stars Cooper and Lawrence in the movie.
The video is the first offering from Jessie since she adopted a more natural new look steering away from the harsh make-up and wacky outfits her fans are used to seeing her in.
