Katy Perry and John Mayer Reunite at Her Memorial Day Party!
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?
