Listen to Justin Bieber on iHeartRadio

Justin Bieber is setting the Internet ablaze with an Instagram photo that may be hinting at a role in the upcoming "Batman Vs. Superman" movie. 

Fans of the pop star and movie franchise have been speculating about his possible involvement in the "Man of Steel" sequel since Friday, when he posted a photo of the script along with the caption "#robin??" 

The singer later tweeted that he was on his way to shoot a sketch for the comedy website, leading some to believe the photographed script could have just been a prop.  

If Bieber does turn out to be the movie's latest casting choice, it would follow their controversial selection of Ben Affleck in the role of Batman.  Henry Cavill will be reprising the role of Superman for the movie, which is due out in the summer of 2015.
