Serious question. Can anyone explain to me WHY the prettiest women are usually the most insecure?

I'm not sure men realize how much of what is said to us women is entirely look-based and those interactions are completely conditional on how we look. Likely the more you are influenced by this....the more insecure or prone to jealosy you will end up being. It's important to be nurtured in a balanced way growing up...

Just like I've known some men feeling insecure when their value is based entirely on what other people think they can do for them or how much they earn, etc. it's very similar.
