Katy Perry and John Mayer are back together. Barfff.
This news comes two-months after their first split, both Katy and John were at her new Beverly Hills mansion for a Memorial Day barbecue with friends according to Us Weekly.
"They seem to be back together -- or back together-ish," one observer tells Us. "They were very flirty and having a really good time together. They have good chemistry."
The duo started casually dating in the summer of 2012, and let's face it - will it last again? Probably not considering he hasn't lasted long with any lady.
