"Movie star, gonna drive around in a fancy car"

 I have a song in my head and the internet is failing me. 

The line I remember is something very similar to "I'm gonna be a movie star, gonna drive around in a fancy car"

I've made an approximate rendering of the tune here, although it doesn't make sense from a music theory perspective so one or both of the higher notes might be a semitone off.

I remember first hearing this song in childhood (so sometime between 1980 and 1990, although it's possible it's older). I remember the singer as being female. It may have been a song in a cartoon.

I have a vague impression that it's from Jem and the Holograms, but none of the titles on Wikipedia's list of songs from Jem and the Holograms match this song.

 

It is not "Drive my Car" by The Beatles or "I’m Stoned in Love with You" by The Stylistics (or any cover thereof).

Does this ring a bell for anyone?
