But...someone will be joining 1D on stage at an upcoming show to sing a song, however, it's a one-off from Niall Horan's pal who's repaying a favor. You may recall Nialler caddied for Rory McIlroy at the recent Masters golf tournament. Well, it looks like they struck up a deal and Rory will be heading to a One Direction show soon.
Look for Rory to join the guys at their September 12 concert at the Gillette Stadium in Foxborough, Massachusetts. Niall told The Sun recently (via Irish Independent): "He's allowed to pick the song, that was part of the deal," adding, "If I went on the bag with him he would come on stage and sing with us. Apparently he's terrible."
Okay, we're looking forward to seeing just how terrible he is – can't be any worse than Niall totally falling over when he was Rory's caddie!
