James McVey is a prolific writer, and obviously draws a lot from his own personal experience. In fact, The Vamps singer just dropped a major truth bomb about one of his sources of inspiration! When a fan tweeted at the guitarist that she was enjoying his old music, he had a sassy response about what happened to the girl who inspired the track, "For Sun and Rain."

James revealed that his ex now has a child, which is kind of mind-boggling to think about!

Obviously, she's just living her life and he's living his, but it's probably strange for him to think of his ex being a mom.
