And we're not just talking about her records! The 27-year-old singer has a heart of gold too, as she spent most of the day on Thursday hanging out with and talking to the students of Frederick A. Douglas High School in New Orleans, Louisiana. The best part? An hour long surprise acapella performance to top it off!

As part of the Lexus Presents the Alicia Keys “As I Am” Tour, the Grammy-winning songstress and Lexus launched “Keys to Innovation,” a program celebrating and honoring inner city high schools across America that have successfully implemented innovative environmental programs. Lexus and Alicia even handed a check to the school to keep up the program as well as chance to submit an action plan to win an extra $10,000 for the school program.
