“It’s like a family – you don’t choose them. Maybe these aren’t people I would have been friends with if I’d only met them once at a party, but this experience binds us together,” she said.

Mendes then explained that although she and her castmates have had their differences in the past, they reconciled after every argument.

“I fought with every one of these girls. We’ve had drama, we’ve had disagreements, we’ve cried, we’ve made up. We’ve been through a lot together and we leaned on each other in those moments,” she said.
