Jennifer Lopez is sending the kiddos back to school!

The “Amor Amor Amor” singer shared a sweet pic to Instagram on Thursday of her 9-year-old twins, Emme and Maximilian, as the young students prepared for their first day of fourth grade.

"So proud of my babies,” the 48-year-old pop star captioned the pic. “#notbabiesanymore #4thgrade #love.”

Not babies anymore is right! The pair looks so grown up, especially compared to a recent throwback snap J.Lo posted of her kids as toddlers.

Have fun at school, Emme and Max!

Meanwhile, Lopez recently teased her newest music video.
