Hilary Duff strutted onto the stage for the first of her two sold-out nights at Madison Square Garden in New York City on Wednesday (Aug. 5), surprising fans by bringing out Good Charlotte to perform the pop-punk band’s 2003 hit “The Anthem.”

While surprise guests haven’t been a staple of the Lucky Me Tour, Duff has consistently been giving fans exactly what they came for by blending nostalgic favorites with her latest material.
