It's been a week since Niall Horan's debut album 'Flicker' was released, and there's no question that it's done extremely well in terms of sales.

The album hit #1 on iTunes in 61 countries and went straight in at number 1 in charts around the world, including Ireland - and it's heading for the top of the US charts, too.

However, many people have been pointing out that the font used on the word 'FLICKER' on the album artwork looks very like a bad word - particularly when you notice it from far away, say... on a billboard.

This is a problem that only Clint Eastwood might understand.
