Alyssa Milano's quick-thinking may have saved her uncle's life.
According to TMZ, her Uncle Mitch was driving the actress on an L.A. freeway on Tuesday when he suffered a medical emergency.
Police say a vehicle hit their car as Mitch fell unconscious, suffering an apparent heart attack. That's when Alyssa jumped into action, reaching over and using her hand to hit the brakes. She gave him CPR until first responders took over.
