Michael said in an interview that "Diana was a groupie who appeared to be dedicated to Michael himself, but in reality was seducing a number of different band members." This song is about Michael coming to the reality that Diana was not the girl he had originally thought she was, and he was making it known that others should be aware of her ways.
"Diana was the perfect and only name for the woman he was describing. Diana is the Roman Goddess of the moon, who was heavenly divine. She, in Greek mythology is known for seducing men into her worship. This is where he gets the dirty Diana. She seducing the guys in the band through young girls who want to be stars. This one in particular speaks of how she takes hold of his heart and even says he's sleeping with her,,and in Greek mythology she could catch you as well in your dreams."
