"X is really hot" is not a spoiler in any sense of the word unless X is in an episodic TV show and a character introduced in the episode that this was mentioned about. In my opinion anyway. In that case, it would be spoilery to say that because people might not know that X is going to be on the show, or they might know that X is, but not know when.

So it's not like the biggest spoiler ever, or anything, but still spoilery under those circumstances.

Of course, this is my opinion only and not intended to make you angry.
