Jennifer Lopez performed for the first time since welcoming twins Max and Emme … at an elementary school.

The new mom, 38, sang “Let’s Get Loud” for a group of eight 10- and 11-year-olds at their graduation ceremony Tuesday, the Associated Press reports.

Students at PS 37 school for autistic children in Staten Island, New York, became obsessed with the Lopez tune after their teacher showed them the video.

They wanted to watch it every day, teacher Kathy Amati told a local paper. Eventually, they learned the lyrics and the dance moves from the video.

They wrote letters to Lopez for an autograph.

“From the minute we wrote the letters, they just automatically thought she would come,” Ms. Amati said.

A response from the singer came Tuesday: One of her reps called, wanting to know the time of the graduation ceremony because Lopez wanted to attend.
