Did Niall go on tour with his ex's new BF?

Having to spend every day with your ex's new girlfriend or boyfriend probably doesn't sound like a fun time. But for Niall Horan, it's just another day on tour. You see, during the Australian leg of their On the Road Again Tour, One Direction was joined by opening act McBusted, whose bassist Dougie Poynter is currently dating Niall's ex, Ellie Goulding. So, did the two ever butt heads? No way! "We're all big enough to not really care… we all have exes, don't we?" Dougie said when asked about any drama. In fact, he and Niall have even written songs together!
