Mel Gibson's Girlfriend Debuts First Single: "Naked, Intimate, Raw Emotion"

A classically trained pianist who hails from Saransk, Russia, Grigorieva, 39, penned every song on the album except for "Say My Name," which exclusively debuts on PEOPLE.com for that she collaborated on the lyrics with none other than Gibson himself.
