Given that Ed Sheeran is Rupert Grint, and P!nk doesn’t look like P!nk, I suspect that P!nk is not P!nk. Off the top of my head, I think there might be a famous effeminate gay man that vaguely looked like that, and upon using reverse image search, I learned that this is James Charles, who is indeed a famous effeminate gay man, and a YouTuber.
