If your job was to look like Taylor Swift, it's hardly a surprise if it actually succeeds.

The brains behind Australia radio show Kyle and Jackie O hired a professional Tay Tay impersonator to stroll through Sydney's CBD as if she were popping out for a cheeky stroll.

The prank worked, for the most part. Even a pair of newlyweds were granted permission to snap a photo with the Swift-a-like.

Seems a bit cruel, really. After all, it does look a lot like her.

But hey, at least that couple will have a cool pic for their wedding album.
