Directioners, look away now...

If there was any doubt that the lads in One Direction could do with a bit of time apart, then that was put to bed today when Zayn decided to have a go at one of his former band mates on Twitter. 

Louis Tomlinson was in spiky form when he commented on a picture posted by producer Naughty Boy, whom Zayn has been working with, saying that he was "riding on the back of someone else's career". Malik responded with a put down that suggests that the relationship between himself and the rest of 1D might be getting frosty, and fast. 

As yet, neither of the two tweets have been deleted, but we can't imagine it'll be too much longer before the PR teams go into damage control.
