Miley Cyrus performs at Mitchel Musso's free concert at The Grove.
Los Angeles, California - 05.06.09
The pop star/actress, who is in the state shooting new movie The Last Song, showed up at Tybee Island's Stingrays with a guitar and treated locals to an impromptu set.
One song she performed was a new tune she had written, which she had scribbled on a piece of paper.
A diner says, "It was a break-up song."
Cyrus recently split from boyfriend Justin Gaston.
