Editors, Labrinth, Emeli Sande, Dizzee Rascal and Stereophonics are among the latest names announced to perform at T in the Park.
The quintet will take to the stage in Balado, Kinross, over the weekend of 12-14 July for the annual music event, with Chase and Status, Everything Everything, Jake Bugg, Miles Kane, Noah and the Whale, Paloma Faith, The View and Yeah Yeah Yeahs also joining the line-up.
Editors drummer Ed Lay said in a statement: "It is our pleasure to be coming back up to T in the Park this summer, after what seems like an age. Editors have undergone some changes in the last 12 months, but we have come out the other side a more determined band with a bunch of new songs that we think you are going to like.
"We can't wait to get back amongst it with some special festival crowds, and where could be a better place to do that than T in the Park?"
Labrinth added: "T in the Park is one of my favourite festivals to play. The crowd is always on fire and I KNOW this year is not going to be any different!"
Tickets for T in the Park 2013 - which will be headlined by Mumford & Sons, Rihanna and The Killers - are on sale now.
