Music stars turn out to see Katy Perry perform in London
Pop superstar Katy Perry has been playing through the UK leg of her Prismatic tour over the past couple of weeks and now she's finishing up a 4-date run at London's O2 Arena, and the stars have been in attendance at the concerts.
One Direction heartthrob Niall Horan took to his official Twitter page this evening (May 29) and told his followers that he had been to check out her new stage show, which he loved: "Gotta love KP at the O2 the other night! She is incredible! Love her."
'Money On My Mind' hitmaker Sam Smith also confessed that he went to one of her O2 Arena shows with Radio 1 DJ Nick Grimshaw and shared a photo from the gig, which he accompanied with the caption: "Just a quiet night in @katyperry."
Perry, meanwhile, uploaded a photograph of herself posing with 'Someone Like You' vocal powerhouse Adele to Instagram and told her fans that the singer had been to watch her live, which was so exciting: "And on the 2nd LDN show the Queen graced me with her presence."
