The Killers will headline T in the Park in 2013 after music fans voted them the act they most want to see perform as part of the Scottish music festival's 20th anniversary celebrations.

The Mr. Brightside hitmakers have topped the bill at the festival three times, and revellers wanted them back to celebrate 20 years of the event next July (13).

Festival director Geoff Ellis says, "The Killers topped our fan poll as the artist our audience most wanted to see in 2013, and we are absolutely thrilled to announce them as our third headliners for T in the Park's 20th edition.

"They're one of the biggest bands in the world, and when we last brought them to Scotland, demand was so high we could have sold out the show four times over."

Rihanna will make her debut at the festival, while folk band Mumford & Sons will also headline.
