T In The Park organisers are reportedly lining up a swoop for Coldplay and Muse to headline next year's festival.
According to industry insiders, Coldplay are ready to come out of their self-imposed exile to unveil their next album – the follow-up to 'X & Y' – at the July festival.
The band's last UK headline appearance was at the Isle Of Wight Festival in 2006, months after they announced a three-year hiatus at the BRIT Awards.
But reports suggest a new album has been readied with a 2008 release due and a European summer tour also planned.
Muse are also a target for next year's T In The Park. It is believed the band were lined up to play last year's event before they opted to play Live Earth instead.
With T In The Park now extended to a three-day festival that would leave just one headline slot to fill.
Other bands rumoured for the 80,000-capacity event include Kaiser Chiefs, The Verve and Orson.
It's all speculation of course, and we won't know anything for definite until T In The Park announces its line up in the new year. It takes place at Balado, Kinross, from 11-13 July 2008.
