Why not just address this as a baby shower...?

Oh, but you don’t understand. The baby shower is an entirely different party.
Next, you are going to tell me that you don’t know about staging engagement events, where one can actually hire people to set up the whole situation in which the hopeful suitor pops the question. It can be an exotic location, or in a hot-air balloon, etc. And your professional can record the whole event to be shown over and over again and posted on Facebook. And, of course, the the blushing maiden pretends to be surprised when she was actually the one who nagged him into doing the whole thing.
My husband and I did music for a wedding last weekend where the couple (probably the bride) were obviously all about the pictures. The photographer/videographer had two assistants, and he was clearly running the thing. (One of the assistants sang along with everything, which was cute.)
LOL, that’s now a picture in my mind.
I can see that clearly.
