After Paul McCartney was the first act announced to headline Glastonbury, many were expecting Taylor Swift and Kendrick Lamar to follow.
This is what the bookies were predicting after all, and given the size of the two acts it wouldn't be beyond the realms of possibility.
And while this could still be the case, a new act has suddenly suddenly been thrown into the mix as a potential performer which has taken everyone by surprise.
This morning, legendary American rock band Aerosmith - currently made up of Steven Tyler, Joe Perry, Tom Hamilton, Joey Kramer and Brad Whitford - announced a major 2020 tour to mark their 50th anniversary.
And NME reports an official listing said the band WILL play Glastonbury on June 27 - the Saturday of the festival.
NME reports an official listing was sent to fans this morning with the European tour dates and included Glastonbury, but Bristol Live has only seen this information on social media and not been sent the original listing.
The tour details posted publicly show the band will perform at venues across America and Europe - and eagle-eyed music fans quickly spotted there is a Glastonbury-shaped hole in their dates.
Glastonbury's 50th anniversary takes place between Wednesday, June 24 and Sunday, June 28.
The rockers are set to play Prague's O2 Arena on June 24 but do not have another show lined up until June 30, when they head to Accorhotels Arena in Paris.
Glastonbury fanatics eFestivals reckon this is enough evidence to suggest Aerosmith will be performing at Glastonbury, possibly headlining.
On Twitter they wrote: "It definitely looks like Aerosmith are heading to the farm. #Glastonbury "
People on social media and in forums have speculated that if the rumours are true they would definitely be a headliner, however others have suggested they could perform before Paul McCartney on Saturday night.
Aerosmith released their first record in 1973 and achieved mainstream fame with their 1975 album Toys in the Attic, which features their well-known song Walk this Way.
In total they have amassed a total of 15 albums under their belt, as well as a string of classic hits including Janie's Got a Gun, Dude (Looks Like a Lady), Livin' on the Edge and I Don't Want to Miss a Thing, which they penned for sci-fi disaster flick Armageddon.
