Rihanna and Mumford & Sons to headline T in the Park
Rihanna and Mumford & Sons have been announced as headliners for next year's T in the Park festival.
The event, Scotland's biggest festival, is celebrating its 20th year in 2013 and will see singer Rihanna make her debut at Balado Park in Kinross-shire.
Mumford & Sons last performed at T when they headlined King Tut's Wah Wah Tent in 2010.
Other artists on the line-up already are Mercury Prize winners Alt-J and Nottingham singer/songwriter Jake Bugg.
Paloma Faith and Icelandic group Of Monsters And Men have also been announced.
Tickets for the event go on sale this Friday (7 December) at 9am.
Festival director Geoff Ellis says: "It seems like only yesterday that the first band took to the stage at Strathclyde Park for our inaugural T in the Park in 1994.
"Here we are in 2012 announcing two of the of the world's biggest and best acts to headline our 20th edition."
Last year's T in the Park was headlined by Snow Patrol, The Stone Roses and Kasabian.
After a sunny start to the 2012 festival, heavy rain fell turning much of the site into a mudbath.
