During the One Direction documentary, Harry Styles was apparently bathing naked in the pool! Well spotted, I’d say. First we see a clip of him coming out of the house only in his boxers. Moment’s later we see him in the pool, only this time his boxers are laying on the side of the (the exact same boxers). The other boys join in as well later, but they have their boxers on. This is in fact true because the staff confirmed it. Sadly, no body parts were shown other than his chest. photo source.
