Beauty and the Beast

Just today, my daughter was watching Beauty and the Beast. It was at the end, when the Beast changes into the prince, and she asked me what was happening. I explained that the spell was broken so the Beast became a prince again. She said, in a very know it all tone, "But mom, he can't change into a prince because it's called Beauty and the Beast, NOT Beauty and the Prince. Don't you know that?"
Obviously I am not well versed enough in my princess movies.
