The former couple is spotted looking flirty during a private, star-studded Memorial Day bash at Katy Perry's Hollywood Hills home...could they be getting back together? Are Katy Perry and John Mayer back on again?
If not, the former couple certainly looked cozy on Memorial Day, when John attended a private party at Katy's new Hollywood Hills home.
"They seem to be back together...or back together-ish," a source tells UsWeekly of the twosome. "They were very flirty and having a really good time together. They were definitely friendly. They have good chemistry together."
Katy and John called it quits back in March for the second time, but a source said Katy was "leaving the window open" for a possible reconciliation.
"Coupling is a tricky thing," John confessed to Ellen DeGeneres shortly after their split.
Do you think the third time could be a charm for Katy and John's romance? Or should they both move on and date new people?
