Jennifer Lopez is worried for her children and loved ones following the school massacre

Jennifer Lopez decried the latest school massacre in the United States on Wednesday, which killed numerous children, and asked for action to avoid such a tragedy from occurring again.

In a shooting Tuesday at an elementary school in Uvalde, Texas, a community of about 16,000 people about 80 miles west of San Antonio, a shooter killed 19 children and two adults.

The “On the Floor” singer expressed her heartbreak on Instagram. “I’ve been emotional and sobbing a lot since hearing about these wonderful youngsters and instructors,” she explained.
