What did you get up to this weekend? Cinema? Pub with your mates?
Not B.o.B. He spent the last few days trying to convince Twitter that the world is flat.
And yes, as you might expect, he's having a tough time getting any of his 2.2m followers to agree that the planet is not in fact round.
Best known for Airplanes, featuring Paramore's Hayley Williams, B.o.B's evidence is largely based on the fact he's never seen the curve of the earth.
When followers suggested he needed to be above the planet to see the curve of the earth.
In response, the American rapper suggested: "No matter how high in elevation you are... the horizon is always eye level".
He posted several tweets to suggest people simply didn't want to accept what he was saying and sympathised, adding "I didn't wanna believe it either".
He also ruled out certain photographic evidence by reminding followers that GoPros have "curved lenses".
However, he didn't respond to a tweet which seemed to show the arc of the earth behind two skydivers.
His latest round of tweets ended with a challenge to his followers to send him a picture showing the curve of the earth, which wasn't taken by NASA.
And of course, he didn't have to wait long.
