1: Niall Horan was asked at a 前 interview によって the one and only Harry Styles, quote: "Who was the last person あなた had sex with?" Harry meant it playfully but I could tell the ni was hiding something. 2: Ed Sheeran wrote "Don't" allegedly about Ellie Goulding cheating on him によって having sex with Niall Horan. This allegation was never confirmed. Conclusion: I'm certain he isn't a virgin. People change.
