Miley Cyrus shocked Halloween revellers in Louisville, Kentucky on Saturday night (31Oct09) - after delivering a surprise rock 'n' roll performance at a local bar.
The 16-year-old star was in town to play a concert at the city's Freedom Hall and was still wearing face paint from her trick-or-treat festivities when she took the stage at the Phoenix Hill Tavern Bar at midnight.
A video posted on TMZ.com shows Cyrus jamming with fellow revellers dressed up as zombies and glam rockers for her rendition of I Love Rock 'n' Roll.
Cyrus reportedly left shortly after the performance.
