The "Señorita" stars teamed up with the Ryan Seacrest Foundation to pull off the epic event.
"When you answer a video call and @camila_cabello & @shawnmendes are on the other end…" a post from the foundation's Instagram account read. "Let's just say, the happy tears are still flowing at @childrensnational."
Cabello and Mendes seemed to have a blast hanging out with the kids, too. They danced to Megan Thee Stallion's "Savage" and answered a few questions. For instance, one child asked the "Havana" artist what social distancing with Mendes has been like. Of course, the "Mercy" artist said "it's the most fun."
"It's the most fun," Cabello agreed. "He made broccoli eggs today. Have you ever heard of broccoli eggs? It sounds terrible, but it tasted great."
