​Are Neil Young and Daryl Hannah dating?

Are Neil Young and Daryl Hannah an item?

The rocker and actress were spotted getting cozy this week during lunch in Southern California. The Daily Mail posted pictures of their get-together, and in one photo, Hannah, 53, gives Young, 68, a big smooch on the cheek. This could very well just be a platonic friendship, however, insiders tell Us Weekly the stars are dating.

"She's a huge Neil fan," a source said. "They've known each other for years." In January, they teamed up for the environmentalist documentary, "Petropolis: Aerial Perspectives on the Alberta Tar Sands."

Young, meanwhile, is newly single. He and his wife, Pegi Young, called it quits in July after 36 years of marriage. Records show that a petition for dissolution of marriage was filed on July 29, in San Mateo, California, where they reside.

Pegi served as inspiration behind some of Young's song and also sang with him in concert at times.

Hannah had long-term relationships with John F. Kennedy, Jr. and Jackson Browne.
