One Direction just launched their North American leg of the Where We Are tour last week in Toronto after a brief break at home. The group's next stop is in Massachusetts at Gillette Stadium.

Despite all of One Direction's success, Simon Cowell recently said that the group had to step up their game due to their openers 5 Seconds of Summer's success. "It does mean 1D have to up their game a bit. We knew a lot of boybands would follow but the competition is tough at the moment," Cowell said according to The Daily Star, published on Sunday. "I think it was a strange decision," Cowell said about having 5SOS open for the boy band, "A bit like the cuckoo in the nest."
