The pair started dating shortly after Portman appeared in Banhart's "Carmensita" video last March.

Portman had asked the musician to donate a song to "Big Change: Songs for FINCA," the charity compilation she put together on iTunes. In return, she agreed to appear in the video for free, People said.

Portman's film credits include "Beautiful Girls," the "Star Wars" prequels, "Garden State," "Mr. Magorium's Wonder Emporium," "The Other Boleyn Girl" and "My Blueberry Nights."
