Naomi Campbell failed to recognise Harry Styles

Naomi Campbell has confessed she failed to recognise One Direction heartthrob Harry Styles upon their first meeting, accidentally mistaking him for a model's son.

During the London Olympics closing ceremony last year (12), the British beauty joined fellow models Kate Moss and Jourdan Dunn as they strutted down a runway.

Backstage, Campbell mingled with other U.K. celebrities who were on hand to close out the summer games, including Styles, who was there to perform with his bandmates.

But in an interview with Heat magazine, Campbell confesses when she first met the young singer, she had absolutely no idea who he was.

She says, "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.'"
