Teen hunk Zac Efron has been hit by a lawsuit three years after allegedly causing a three-vehicle pile up in Los Angeles.

Katie Porter claims she was rear ended by a taxi, which was shunted by the vehicle the High School Musical star was driving back in 2006. The plaintiff states she has spent the past three years fighting for damages with the insurance companies, and she's had enough.

Porter's mom tells TMZ.com the firms representing each of the drivers is claiming the other is responsible for repair costs.

The alleged crash victim wants $1,200 for repairs and $400 for a rental car. Her father, who lives in Oklahoma, is also suing for plane and motel costs.
