Jennifer Lopez took time out from looking after new newborn twins, by performing for a New York elementary school’s graduation ceremony.

The pop star was contacted by the students at Staten Island's autistic school P.S. 37 after teacher Kathy Amati showed them the video for Lopez's single Let's Get Loud.

The kids loved the promo so much, Amati suggested they write to Lopez in the hope of getting autographs or pictures in return.

But they were stunned when Lopez personally requested to perform at their graduation ceremony - and the group of 10 and 11-year-olds were treated to a private performance on Tuesday, where she sang Let's Get Loud especially for them.
