Demi Lovato + Nick Jonas

Pop starlette Demi Lovato and the youngest Jonas bro roll into town on their Future Now tour. The Disney alumns are hardly strangers: This is the sixth time they've joined each other on the road and the pair launched a record label together last year. Show up for a double dose of R&B- and trap-tinged pop—and plenty of sing-for-the-rafters hooks.
