Pop star Nick Jonas delighted scores of teenage fans on Tuesday (02Feb10) when he performed an impromptu acoustic set in Santa Monica, California.
The Jonas Brothers star, 17, has been touring the U.S. with his band Nick Jonas and The Administration, since unveiling the side project last year (09).
And he decided to give fans by the Southern Californian pier a surprise treat when he broke into song, backed by his guitarist Sonny Thompson, before posing for photos with his devotees.
