Harry Styles has said that Simon Cowell would not trust One Direction members with his mobile number.
The 17-year-old singer, who was mentored by Cowell on last year's The X Factor, revealed how he let slip Matt Cardle's number with Louis Tomlinson via Twitter.
In an interview on Hits Radio, Styles said: "We would not be trusted with his number because me and Louis once gave out Matt's number on a Twitter cam."
The singer, who is gearing up to release One Direction’s new single What Makes You Beautiful on September 11, added: "It was an accident, don't judge us. I don't think Simon would take it as well as Matt did."
