Which Lady Gaga persona do you think will get the most action this Halloween? Jo Calderone? YuYi the mermaid? Skull-faced “Born This Way” Gaga? Or perhaps some sort of Classic look, with a Kermit coat or a hair bow? Practically every look the pop star ever sported is represented here in “This Is Gagaween.” Using the opening song from The Nightmare Before Christmas, The Hillywood Show presents the spookiest, most on-point parody of the singer this Halloween season. Seriously — it’s scary how much the woman in the clip really resembles her. Maybe this is Gaga tricking and treating us all?
