ZOMG, we don't believe it!!
OK, we totally do!!
According to one source, the Hot N Cold couple had more chemistry than a Breaking Bad marathon!!
"They seem to be back together — or back together-ish. They were very flirty and having a really good time together. They have good chemistry."
Holy shish-kabobs, we never would've thought those flames could be rekindled!!
Last we heard, she was playing "hide the sausage" with an agent friend and Johnny boy was just The One That Got Away!
Another source confirmed:
"They were definitely friendly."
Other celebz at Katy Kat's party included Mindy Kaling, BJ Novak, and Girls star Allison Williams.
As far as we know, Miss Perry was considerably less flirty with all of them.
