One Direction star Louis Tomlinson has expressed his sadness after the boyband's Comic Relief single leaked online ahead of its official premiere.
A low-quality version of their cover of the Blondie hit One Way Or Another has emerged on the internet ahead of its release on February 17 - leaving Tomlinson to take to Twitter to urge fans to pre-order the song instead.
The 21-year old tweeted: "I hear the charity single has been leaked. Very sad to see. Don't forget together we are trying to raise money for comic relief."
He added: "Please get behind an incredible charity and make a real difference. You can pre order now from iTunes for the official track. Thank you."
1D are set to perform the song - which also samples Teenage Kicks by The Undertones - for the first time at The Brit Awards on February 20.
