If you were born handsome, is the attention more likely to make you introverted or extroverted?

1.
Let’s say there’s a baby, who is naturally very handsome or beautiful. Probably the type of attention they will receive growing up (both from adults and their peers) will be quite different. Are they more likely to be extroverted or introverted as a result of this attention? Or does it not matter? Is there something that genetically predisposes you to introvertism/extrovertism that is independent of what you look like?

2.
What if we acknowledge that physical beauty is not inherent, but the result of care and management? (i.e., instead of appearance causing introvertism/extrovertism; it’s the introvertism/extrovertism that causes an attentiveness to one’s appearance.) Is an extrovert is more likely to care about what other people think about their appearance, and groom themselves better? Or is the pretty cheerleader/ nerdy nerd myth bogus?

[note: there are many assumptions in this question about introvertism/extrovertism and the nature of beauty, but for this question, let’s play along and pretend that introvertism/extrovertism are opposites, and that the beauty discussed here is just about physical appearance…]
