As I said VH1's Divas is a party and celebration with a purpose.  The show will benefit the VH1 Save The Music Foundation, a non-profit organization dedicated to keeping music education alive in American public schools.  As a matter of fact to date, VH1 Save The Music has provided more than 49.5-million dollars in new musical instruments to 1,850 public schools in more than 128 school districts around the country, impacting the lives of over 2.1-million children.  Now that's what I call a purpose.
