Katy Perryhas reportedly rekindled her romance with John Mayer for the third time.
Perry - [uuid=015d3740-83e0-4bd4-a4f3-0d2dd5d441f5]who split from Mayer in March[/uuid] - is thought to be 'casually dating' the singer/songwriter again, after reuniting at K-Pez's Memorial Day party at her new home in the Hollywood Hills.
A source told E! News: “They are just hanging out. They are not putting a label on it.”

An partygoer also told Us Weekly: "They seem to be back together — or back together-ish. They were very flirty and having a really good time together."
Despite rumours of a reconciliation, Mayer previously hinted to chat show host Ellen DeGeneres that he was "happier" being single, stating at the time of their break-up: "I’m on the same journey as everyone else. Coupling is a tricky thing.”
When Ellen asked him whether he had split with Perry for good, Mayer replied: “Correct.”
Katy and Mayer are yet to comment on the reunion reports.
