In the beginning of a song, Ranbir is standing near a window with only his towel on. It is made very evident that he is completely nude as he pulls it down just enough to see a better portion of the side of his bare butt. After a while, he whips it off and the towel slips from his hand. The scene cuts before we see his bare butt. This is from the Indian version but in others, the nude scene might be present.
