"Grey's Anatomy" star Patrick Dempsey turned real-life hero on Tuesday when he pulled a teenage driver from a wrecked car after a serious accident outside his Malibu, California, home.
 
The TV hunk, who plays top neurosurgeon Dr. Derek Shepherd on the hit medical drama, raced into action after witnessing the young motorist's Mustang flip over several times and crash into his front yard.
 
According to TMZ.com, Dempsey used a crowbar to free the boy from the wreckage as he waited for paramedics to arrive on the scene.
 
The crash victim, whose name has not been released, had an extremely lucky escape - he suffered a concussion but did not sustain any serious injuries.
 
Dempsey is familiar with car crashes - he spends much of his spare time racing.
