It looks like Alt-J might've accidently let slip that they're going to be on the Glastonbury lineup, before the lineup's been announced.
Michael Eavis probably won't be happy, but it would seem in a moment of absent-mindness the Mercury Prize winners have confirmed themselves for the mega-festival.
In a live interview with James Corden at the BRIT Awards last night, the band were asked about their summer plans.
"Yeah, we're playing Leeds, Reading, Glastonbury, we're playing around Europe as well," the band replied.
The initial line for Reading and Leeds has already been announced, but Glastonbury's lineup is still a closely guarded secret, fuelling frantic speculation among ticket-holders.
Rihanna is apparently being lined up to headline on the Sunday night, and The Rolling Stones are said to be 'seriously considering' a £1million offer to play the event. Arctic Monkeys are also rumoured to appear.
Have Alt-J let slip that their playing Glasto?
Alt-J were nominated for three awards at the BRITs last night, putting them level with Emeli Sande and Mumford & Sons.
But the boys walked away empty handed, while Sande took two awards for Best British Female and Best British Album while Mumford took Best British Group.
They'll just have to console themselves with their much coveted Mercury Prize.
