Supermodel Naomi Campbell shocked Kate Moss when she didn't recognise One Direction's Harry Styles.
Campbell is close friends with Moss and left her stunned at the London Olympics closing ceremony last year when she didn't recognise the teen idol after Moss introduced the pair.
Speaking to Heat magazine Campbell said, "Kate introduced me to him at the Olympics. And I said to her, 'Whose son is he? Is he one of our model friends' kids that I just missed out on?' I didn't know who he was.
"Kate was like, 'Stop! No! You must know him'."
Campbell also revealed to Heat that she gets star-struck at times, "Of course I get star-struck, but I don't run up to the person, I just look from afar.
"I saw Michael Douglas' dad Kirk in Cipriani in New York once. He said, 'Come here young lady.' I was like, 'Oh my God'."
Naomi Campbell can be seen hosting her new modelling show The Face on Sky Living, Mondays at 9pm.
