Natalie Portman and Musician Boyfriend Split

09/24/2008 at 07:30 PM EDT

Natalie Portman and her folk-rocker boyfriend Devendra Banhart have broken up, a source confirms to PEOPLE.

Portman, 27, began dating Banhart, also 27, after starring in his "Carmensita" video, which was shot last March. A short time later, they took their romance public when they were spotting kissing on the streets of New York and over a sushi dinner at Jewel Bako.

A fan of Banhart's music, Portman had asked him to donate a track to the charity compilation she curated on iTunes, Big Change: Songs for FINCA. She returned the favor by forgoing her usual fee to appear in the video.

"They got together right after the video shoot," a source said at the time.

They also traveled together to Cannes and to Israel.
