One Direction have revealed that their boss Simon Cowellwon't let them have his phone number.
Matt Cardle's mobile number on Twitter cam.
Styles told Hits Radio: "We would not be trusted with his number because me and Louis once gave out Matt's number on a Twitter cam."
The 17-year heartthrob added: "It was an accident, don't judge us. I don't think Simon would take it as well as Matt did."

We very much doubt it...
