In a very strange and unprecedented set of affairs, a load of eagle-eyed football fans think the wife of Manchester City centre back Nicolás Otamendi - Michele Otamendi - has six toes on one of her feet.
Now, football fans can be pretty cruel about this sort of thing - am I right, Norwich City fans? - but upon closer inspection of the picture, it might actually be true.
If you look very closely at the left foot of Mrs Otamendi, you can just about see there could be an extra tootsie on show.

Of course, there's nothing at all wrong with that - some people just have extra fingers and toes - but it is unusual and therefore worthy of remark.
And boy, do football fans like to remark.
Obviously, it's worth pointing out at this stage that we have no idea whether Mrs Otamendi actually has an extra digit or not. It could just be a trick of the photograph, or a bit of her shoe that is sticking out.
Basically, it just looks a bit like it. That's enough for the good folk of the internet, though.
Nicolás Otamendi, whose Manchester City team just wrapped up an historic domestic treble with a thumping six nil victory against Watford in the FA Cup final on Saturday, shared the (now) controversial picture with the caption: "Champion's Party"
It appears to have been taken at some sort of civic reception for City manager Pep Guardiola and his record-breaking team at Manchester Town Hall earlier this week.
Pep and his team retained the Premier League title, holding off an excellent challenge from Liverpool. On top of that, they won the League Cup back in February.
Add to that the aforementioned FA Cup triumph, and there is a lot to celebrate for the Otamendi family this season.

As for the phenomenon of having more toes than most people, it's called polydactylism and it affects about one in every 500 people.
Ordinarily it is just a piece of superfluous tissue that can be easily removed, however sometimes it can contain a bone without a joint, or - in rarer cases - be a fully functioning digit.
That's great news if you're a jazz pianist, at least.
Anyway, it's worth re-iterating that we have no idea whether this is even real. It could just be an optical illusion.
Have a zoom in and see what you think...
