No, it's the fan. It makes sense because the guy is calling them traitors and she responds with "we're fans." Why would Lana say "we"? The guy clearly isn't a fan.
how would you know he's not a fan?
and lana said "we" meaning her and francesco.
Truth be told there are many outcomes, so we are all just assuming.
That Gaga stan's voice is like nails on a chalkboard and Lana's body language/tone seemed very insincere, I'm guessing she just didn't want to look rude and wanted to end the conversation. It's been pretty well established that she's not a fan...
and never will be
