J.Lo performs at elementary school graduation

NEW YORK -- Students at a Staten Island, New York, elementary school for autistic children sure like the way Jennifer Lopez moves.

Teacher Kathy Amati and a paraprofessional showed the video for Lopez's "Let's Get Loud" to the students at P.S. 37. The children liked it so much, they wanted to watch it every day.

They learned the lyrics and the dance moves from the video.

With their teacher's encouragement, they wrote to Lopez, hoping for pictures or an autograph. Instead, she asked to come to their graduation.

On Tuesday, the singer-actress performed "Let's Get Loud" for a group of eight 10- and 11-year-olds at their graduation ceremony.
