Don't be fooled by their tight pants and curly locks, One Direction is smarter then they look! These boys have been extremely supportive of their tour buddies, 5 Seconds Of Summer. 

It may just seem like a harmless tweet, when in reality it may not be what it appears. The 5SOS trademark means that they technically own a 50 per cent stake, which profits with a 10 per cent share. 

So pretty much to sum it up.. the more successful 5SOS is, the more money 1D makes!! Can you blame them??
