Zac Efron: Let's Go Racing

Zac Efron hops inside his race car as he continues to film scenes for Heartland in Newton, Iowa on Sunday (July 17).

The 23-year-old actor plays the son of Dennis Quaid, who has dreams of racing but his dad has others.

Later that night, Zac was spotted in Chicago — grabbing a later dinner and then stopped in for a drink by the bar at Sunda before heading over to the Underground for the club’s weekly dance party. When a five-minute medley of Michael Jackson tunes started to play, Zac got down on the dance floor.
