Young and Beautiful

The verse goes

Will you still love me when I'm no longer young and beautiful?
Will you still love me when I got nothing but my aching soul?

She's showcases her insecurities by asking if she would still be loved when she has nothing

I know you will, I know you will, I know that you will
Will you still love me when I'm no longer beautiful?

Here she hopes and reassures herself that he most certainly will

In some of the other verses, you can still see references of "his" features

Yourpretty face, and electric soul

All that grace, all thatbody
All thatface makes me wanna party

Isn't she obsessed with his physical features but is insecure whether she will be loved when she loses hers
