Katy Perry takes selfie with Adele
London: Pop star Katy Perry posted a selfie with Oscar-winning singer Adele after meeting her at London`s O2 Arena.
Perry, 29, called her `Queen` Adele after she attended the second night of her four-show residency in the capital, reportedly.
"... And on the 2nd London show the Queen graced me with her presence," Perry said.
Adele is the latest star to enjoy Perry`s Prismatic World Tour, after Sam Smith, Nick Grimshaw and Jessie Ware. The `Roar` hitmaker launched her new world tour in Belfast earlier this month, before visiting cities like Liverpool, Manchester and Nottingham.
