Katy Perry is lined up as one of the top acts at the concert to celebrate the coronation of King Charles next month. She will no doubt be dipping into her catalogue of sure-fire hits like Firework and Roar - but fans want to her to sing something in particular.
Perry has been appearing in adverts for food ordering app Just Eat, singing the company's jingle 'Did somebody say Just Eat?' while dressed as a giant ice cream, as well as eating pizza with a giant chunk of cheese perched on top of her head. The promotion's popularity means people have called for the star to give the tune an airing to honour the new monarch.
Writer Jason Reid @JasonReidUK said on Twitter: "How am I just finding out that Katy Perry is to perform at the coronation? I hope she sings her Just Eat song."
