Hilary Duff: Why Not

"Why Not" is the debut single recorded by American actress and singer Hilary Duff for the soundtrack of the 2003 comedy film, The Lizzie McGuire Movie, which was produced and released at the time when Duff was starring as the title character of the Disney comedy series Lizzie McGuire. The video shows Duff singing from a rooftop; this is inter-cut with scenes of street scenes of skipping, break dancing and crowds running, as well as waist shots of extras mouthing the words.
