Lipa had turned in a stunning Friday night headline set, but was walking through a (presumably exclusive) area of the festival when she was stopped by a man with a ukulele, who introduced himself as 'Liam C'.

He asks her whether he can play '30 seconds' of his song for her, and her reaction as she stands there - forcing an awkward smile as she frantically tries to plan her escape - has already become a meme.
