Example sentence: I've never been unfaithful outside 'Made In Chelsea.' I don't care what the reputation looks like. I was unfaithful on that television show because it's a show about that. I'm not saying it was acceptable behavior, but the show wouldn't work without relationships failing. In real life it's completely different.
