Brad Pitt fears he has a memory disorder which stops him from recognising the faces of people he has previously met.
The Hollywood superstar often finds himself in trouble with acquaintances who he fails to remember - but is adamant his inability to recognize a face is down to suffering prosopagnosia, and not his inflated ego.
He tells Esquire magazine, "So many people hate me because they think I'm disrespecting them. So I swear to God, I took one year where I just said, This year, I'm just going to cop to it and say to people, 'OK, where did we meet?'
"But it got worse. People were more offended. Every now and then, someone will give me context, and I'll say, 'Thank you for helping me.' But I p**s more people off. You get this thing, like, 'You're being egotistical. You're being conceited.' But it's a mystery to me, man. I can't grasp a face and yet I come from such a design/aesthetic point of view."
Prosopagnosia impairs patients' ability to recognize faces, and Brad Pitt is determined to get tested for the condition soon.
He adds, "You meet so many damned people. And then you meet 'em again. I am going to get it tested."
