Hayden is best known for her role as Claire Bennett in the hit TV show 'Heroes' but she's moved upwards and onwards since then!

She showcased her incredible singing voice in 'Nashville' and has taken part as an animal rights activist when not in front of the camera.

It's good to see some celebrities using their fame for a great cause and to help raise awareness!
