Is this true?!regine velasquez holds 8 octaves?

Regine Velasquez is widely famous for her effortless and exceptional belting. She credits this from her father's vocal training technique wherein she is submerged in neck-deep waters and she runs through her singing exrecises to strengthen her diaphragm and build up her vocal cords and lungpower. This paved the way for a genre of belting for female singers in Philippine music. Her vocal style has been greatly heard in many female singers and has influenced the likes of Kyla, Sarah Geronimo and Rachelle Ann Go. BUT I DON'T KNOW IF SHE HOLDS 8 OCTAVES. sorry!
