Harry Styles loves a random tattoo, but his latest addition is somewhat, erm, interesting.

The One Direction singer debuted the inking of a mermaid in all its glory over the weekend, as he signed autographs for lucky fans.

[related]You may be thinking, 'Oh, a mermaid is pretty harmless, just like The Little Mermaid', but think again, as this one's pretty explicit as it shows off all of the mythical creature's body.

Harry recently revealed that the fishy inking was because he is a mermaid himself, though we're not sure is that's one hundred percent fact...

Though the trusty Directioners have been filling our mind with theories about the new tat, including that it could be a tribute to Cara Delevingne who plays a mermaid in new movie PAN.

What do you think it's all about?
