The snap of Kells - posted on some random's Instagram account - shows the model all naked from the waist up with some kind of fur draped around her neck.
Turns out the pic is about EIGHT years old and from a rather risque shoot with Arena magazine. Phew! For a minute there we thought Kelly was on a one woman mission to bring back side boob.
