Justin Bieber's Instagram is often quite mysterious and his latest post is no different, but could he be taunting Scott Disick with this cryptic pic?

We just don't know.

Bieber shared a photo where he appears to be standing over a woman with the caption "Lord knows".

We're left wondering, could this caption be a reference to Scott Disick's nickname, 'The Lord' and could this woman be Kourtney Kardashian?

Even with our best detective hats on,we can't really work out what the deal is with this pic…

It looks as though the picture hasbeen edited to remove the identity of the woman with lots of people saying it's the 'Keeping Up With The Kardashians' star.

Instagram tells us they've hung out before with the 'Sorry' hit maker being a good family friend of the Kardashians.

But naturally this post has sent fans into a bit of a frenzy,adding fuel to the ongoing fling rumours between the pair.

We don't know what you're up to Biebs, but some answers would be nice...
