Is my girlfriend a good singer?

I am just trying to get her to be realistic because she thinks she can
be a professional singer. I love her, but I honestly think she is
more of a pretty face with only an average voice. Please, no you are
a jerk messages. We are at an age where people need to find a
realistic career.
