This just in: Jennifer Lopez has a heart, it beats and everything! Apparently students at an elementary school for autistic children wrote the singer after their teacher, Kathy Amati, got them hooked on Lopez's video "Let's Get Loud."

The kids sent Lopez the letter hoping to get a signed autograph. Instead, they got Lopez herself, who performed the song at their graduation ceremony.

On Tuesday, Lopez performed "Let's Get Loud" for a group of eight 10-year-olds at their graduation ceremony. The kids, who had memorized the dance moves and lyrics to the song, were obviously thrilled. Since her marriage, Lopez has stayed out of the spotlight. However, she recently announced plans to co-executive produce, co-create and star in this "docu-series" that will show "how Lopez juggles her career - including launching a new fragrance - with motherhood" on TLC.
