In other One Direction news, the lads are said to be 'furious' with fellow UK boyband The Wanted after member Max George appeared to bad-mouth 1D, apparently calling them "children's magazine based." A source told Heat magazine: "They're angry about The Wanted slagging them off. They think it's a low blow and they were shocked that Max would say that."
