Katy Perry reunites with Robert Ackroyd - report

Katy Perry has reconciled with Florence + The Machine guitarist Robert Ackroyd almost two years after they split, according to a new report.

The Firework hitmaker dated the British musician in 2012 following the disintegration of her marriage to Russell Brand the previous year (11).

Their romance fizzled out after several months and Perry began a new relationship with rocker John Mayer, but she has reportedly reunited with Ackroyd, with reports suggesting they were seen kissing at an afterparty for her Prismatic tour date in London over the weekend (30May-01Jun14).

A source tells Britain's The Sun, "Katy and Rob seemed to be very much back together at her party on Saturday night. They were inseparable, kissing, flirting and cuddling away in front of the roadies, celebs and friends at the bash. There were a fair few famous faces in the room but Katy and Rob only had eyes for each other."

Perry split from Mayer earlier this year (14).
