He must be kidding... right?!

Yesterday, Justin Bieber took the internet unawares when he posted a picture of a Batman Vs. Superman script with the caption "#robin??"

While it's certainly possible that the 19-year-old pop star got his hands on a script from the highly anticipated superhero film, he did hint earlier that it could all be a hoax via Twitter.

"Off to do something funny or...die :)" Bieber tweeted on Friday, adding to the speculation that it could all be a big joke.

So is this all part of an elaborate comedy skit or the real deal?
