There are a lot of celebrities that harbour strange conspiracy theories but this might be the strangest (or at least the funniest) one yet.Β 

Rapper B.o.B. has been sending out a series of tweets recently in order to prove his belief that our ancestors were right and the world is actually flat. No, seriously.

He's putting out photographic evidence to back up his claims too.

He also thinks the answers to this 'conspiracy' may lie in the North Pole.

He's taking it upon himself to be our champion in regards to this matter.Β 

Of course he brought up the moon landing too...

That old chestnut.

Just remember folks...
