America's little brother/sister

The actor/singer/celebrity that could be the little brother or sister of anyone with a little brother or sister, since this person actually was somebody's little brother or sister growing up.

If the singer/actor thought his/her boy/girl next door image was bad, he/she could have always got stuck with the America's little brother/sister image of the other actor/singer/pop star.
