Robbie Williams addresses Glastonbury rumours

Pulp tried to quash the rumours, Robbie Williams was happy to fuel them - sharing a picture of a blue plaque in his name apparently slapped over a famous Glastonbury sign, before seemingly backtracking.

"30 years later..." he captioned his first social media post early on Friday morning - a reference to his headline-grabbing attendance in 1995. This was the year Williams was famously pictured partying with Oasis's Liam and Noel Gallagher, shunning the boyband shackles with bleached-blonde hair and a blacked-out tooth.

The writing was on the wall, and the announcement of his departure from Take That came just a few weeks later. At Glastonbury this year, is the writing quite literally on the wall for a comeback? Well, maybe not.

A few hours after his post, Williams shared another, less cryptic message to say he would not be performing, along with his list of recommended acts to go and see - The 1975, Busta Rhymes, Charli XCX, Self Esteem and Reverend And The Makers, if you're interested. Is he bluffing? Double-bluffing? Who knows, but along with celeb spotting and mud, if there's one topic of conversation that makes headlines when it comes to Glastonbury, it's speculation about secret artists.

Williams has got everybody talking. Even before his posts, the Let Me Entertain You singer was among the artists rumoured to be performing secret sets this year, along with Pulp and Haim.

Lewis Capaldi and Lorde too, with both "TBA" acts turning out to huge crowds on Friday. In recent years, these surprise sets have turned into some of the event's most memorable moments - think Foo Fighters as "The ChurnUps" in 2023, Pulp's comeback in 2011, and Lady Gaga treating fans to a small performance in one of the festival's after hours areas, Shangri-La, in 2009.

Franz Ferdinand, famous for hits including Take Me Out and Do You Want To in the mid-2000s, were the first to do it back in 2008. This was actually due to Pete Doherty's band Babyshambles pulling out last-minute, but the approach to announcing the switch was, at the time, a novel one.

While officially, the act was "TBA.
