Jennifer Lopez melted hearts last week when she answered fan mail from a group of autistic sixth graders with a live performance of her 2000 single “Let’s Get Loud.”

Jennifer wowed students at Staten Island, New York’s P.S 37 with a surprise concert during their graduation ceremony, The National Enquirer reports.

A teacher had used La Lopez’ vid for Lets Get Loud as a teaching aid — the boys liked it so much they watched it everyday – mastering the lyrics and moves…..Hoping to get an autographed picture from their idol, they wrote to Lopez…..Instead Lopez shocked the students with a live performance of their favorite.
