Glastonbury Festival has been compared to an aerobics class as fans slammed the announcement that Katy Perry and Stormzy will perform.

The musical pair will share a stage with the likes of Radiohead and Foo Fighters at the Worthy Farm event in June.

They were unveiled as two of the 88 acts set to play the iconic festival including Clean Bandit, The XX, Alt J, Barry Gibb, Biffy Clyro and Solange Knowles.

But some took aim at the decision to book Perry and the London-born grime artist for what some claimed is a rock event.

Another posted: Stormzy n Katy Perry at Glastonbury. ...f****** hell.

Others defended the decision with one posting: Lets face it @katyperry is going to SLAY Worthy farm. Glasto will be big fun this year. Good lineup there #Glastonbury2017 #Glastonbury.

Another wrote: Glastonbury lineup is rubbish except Katy and Stormzy.

The line-up was unveiled by organiser Emily Eavis, daughter of founder Michael Eavis.
