'Little Women: L.A.' Star -- Ass Is The Star Of My Music Video

"Little Women: L.A." star Terra Jole and her friends are just shakin' what their mamas gave 'em ... starring in a new music video that celebrates the beauty of booty.

We're told "Booty Bee" is the first music video with a little person -- Terra -- in the starring role.

Terra -- who's become a little famous playing Mini Britney and Mini Gaga -- not only sang and danced in the video ... she also wrote the music and lyrics.
