Liam Gallagher has taken to his official Twitter account to tease a “massive announcement”, sending the rumour-mill into overdrive.

Posting moments ago, fans have been hoping that the former Oasis-frontman will finally reveal details of his long-awaited solo debut album (of which he has reportedly finished, with the first single expected to be Wall of Glass), however Glastonbury goers seem to be hoping for something much much bigger.

Earlier this month, Emily Eavis revealed that a “big surprise” was on the horizon for next month’s event, the last Glastonbury before Worthy Farm receives its regular fallow year break. With various Glastonbury line-ups already having received the light of day, and the final listing expected to arrive in a matter of weeks, some are speculating that Liam’s announcement will be a surprise return to Glastonbury for Oasis, the first since their split back in 2009. However, with all three headline slots already filled (Radiohead, Foo Fighters and Ed Sheeran), we’d be surprised if any of these are bumped in favour of Noel and Liam’s return to the Pyramid Stage. Noel has previously confirmed his attendance to Glastonbury for 2017 (though not in any specific performing capacity). Speaking to Radio X last month on the progress of his new album, he said “I’ve been given the deadline which is to have everything finished – mastered, artwork, videos, the lot – done by the time I go to Glastonbury in June.”

One thing’s for sure though, we’ll hear all the answers tomorrow! Stay up to date with all the developing Glastonbury news over on our Twitter account, here.
