Katy gets back with former beau

Katy Perry has reportedly reunited with Florence and the Machine guitarist Rob Ackroyd.

The 'Birthday' singer has been spending lots of time with her former flame - who she initially dated in 2012 after meeting at Coachella festival - while in the UK for her Prismatic World Tour, and the pair weren't shy about flaunting their romance at an afterparty to celebrate the end of the European leg of her worldwide jaunt.
