“She did tell her entire school that the Jonas Brothers were coming back — before the Jonas Brothers were [officially coming back],” Kevin revealed.

“We were trying to keep it a secret for basically a year,” Nick explained. “We were making this documentary [Chasing Happiness], making the album. And we’re like, ‘We got this on lock. No one’s gonna tell.’ Kevin comes home and says, ‘Guys, Alena told her whole class.’ Luckily, those 5-year-olds [were] tight-lipped.”
