Courteney Cox received a huge shock when she paid a visit to The Sun newspaper's office in London.

The former Friends actress came to the tabloid's headquarters to research her role as a ruthless magazine editor in US drama Dirt - and was horrified by her findings.

She told WENN: "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?'

"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."

Dirt airs on Mondays at 9pm on Five US.
