What is goodnight pretty lady?

"Goodnight Pretty Lady" is typically a phrase that might be used in a song, poem, or piece of creative writing, but without specific context, it could refer to various things. It doesn't specifically denote a well-known song, book, or film title up to my last update. If you're referring to lyrics, a book, a movie, or any other work by that title released after October 2023, I wouldn't be able to provide information about it.

If this is a recent release or a specific cultural reference, you might want to check the latest sources online or clarify further so I can help you find the information you're seeking.
