Courtney Cox, currently starring as a hard-nosed magazine editor in US drama Dirt, got quite a reality check when she visited the offices of The Sun in London this week.

Cox was visiting the paper to research her Dirt role, and was surprised to learn exactly what sort of research they had already done on her.

"An editor said: 'Courteney, do you want to see what you've been doing for the past couple of weeks while you've been in Europe?'� Courteney told WENN.

"Then he showed me pictures from the week before, when I had been in Sardinia, pictures of when I left the London hotel I was staying in half an hour before, pictures of me in my car, pictures of me arriving at The Sun.

"Even a shot of me opening the door to The Sun five minutes earlier."
