"It's really easy to stay grounded because my [of] band," Caillat tells PopEater during a recent performance in our studio. "I'm with them everyday, we're on the tour bus together and we're all such good friends. They're like my big brothers and we just constantly joke around and have fun together. If we have spare time, we like to relax, go to the beach [or] play music. It's easy, you just stay yourself and do what you love to do."
