Her and her look-alike son remind me of characters in some weird movie by David Lynch
Aging Hollywood sexpot psychologically tempts and torments teenage son with her overt sexuality.
In order to overcome his Oedipal attraction to her, he transforms himself into her physical double, denying his heterosexual masculinity because he knew it was wrong to feel that way about ones' own mom.
He would probably wind up running amok on a bloody, psychotic killing spree at the climax of the movie, killing off her sleazy gigolo boyfriend and several others.
