Another video, posted by the Ryan Seacrest Foundation, showed a fan asking Cabello how fun is it to be stuck at home with Mendes.

"It’s the most fun," Mendes answered for her, and she agreed. "He made broccoli eggs today," she said. "Have you ever heard of broccoli eggs? It sounds terrible, but it tasted great."

As Cabello previously revealed, Mendes has been teaching her guitar, while she's been teaching him Spanish.
