Nicola Roberts and Cheryl Cole were very unworldly before they joined Girls Aloud 10 years ago.
They got together after winning Popstars: The Rivals in 2002 and found they had a lot to learn.
Nicola, 26, and Cheryl, 28, definitely weren't up with the latest technology.
'A car came to pick me up with a sat nav,' recalls Nicola.
'I got in the car and said to the driver: "You what? You're trying to tell me that computer can tell us how to get there? I do-not-believe it."
'Put it this way. [Cheryl] didn't know what a sat nav was either.'
