Julie Brown 's song `` Cause I 'm a Blonde '' was added to the movie Earth Girls Are Easy .
The film underwent more than five months of post-production tinkering , including the removal of the production number `` I Like 'em Big and Stupid '' ( a different version of the song plays in the club ; the deleted sequence appears on the DVD extras ) and reshoots ( the song `` Cause I 'm a Blonde '' was injected into the film late in the game ) , by which time the De Laurentiis Entertainment Group had filed for bankruptcy .
