Katy Perry's appearance at the Golden Globes has caused quite a stir.

First there was that rather flirty ecounter with Orlando Bloom at the Weinstein/Netflix afterparty, and now a photo of her serving champagne at the ceremony has gone viral.

Why was Katy Perry was serving champagne? We still have no idea, but what we do know is that a full on photoshop battle has commenced over on Reddit. 

The thread, which has quickly gained momentum, has a number of dedicated users posting some very creative photoshop transformations and yes, they are funny. Very funny.
