Paulina Rubio : Accused of 'BEATING' Male Assistant

In his suit, Felipe claims Paulina got incredibly violent toward him once they boarded the plane ... unleashing a flurry of punches, kicks and even slaps. He claims she also pelted him with various objects.

Felipe claims he suffered serious injuries from her attack -- including abrasions and contusions on his shins and arms. He also claims he suffered emotional damage.

Felipe says he quit his job as soon as they returned to Miami ... and now wants Paulina to fork over more than $250k to make things right.

It's not the first time Paulina has been accused of having a short temper -- she was arrested last year after allegedly getting into a screaming match with police in Florida.

We reached out to Rubio's camp -- pero no respuesta.
