Nick Jonas Charms Us Behind The Scenes At 'How To Succeed In Business Without Really Trying' (VIDEO)

If it seems like getting your weekly Nick Jonas fix is hard to come by lately (we feel your pain!), it's for good reason: The youngest Jonas Brother's taken a break from his rock star status to offer that boy-next-door charm to Broadway's musical comedy "How To Succeed In Business Without Really Trying" as the lead role of J. Pierpont Finch. Judging by Nick's own successful career at the RIPE AGE OF 19, we pretty much think he has this gig in the bag.

A behind-the-scenes video shows the crooner preparing for a photo shoot playing his new part -- a quirky, bow tie-obsessed, suit-wearing business tycoon. Nick chats about the character's style and how honored he is to have the gigantic opportunity. We even hear flattering compliments about Nick (duh!) from his adorable costar Rose Hemingway. But most noticeably: How in the EFF is Nick Jonas so poised at 19?! We've heard of old souls, but he's seriously more mature than most 30-year-old men I know. But that's a different post...

Nick takes over the role full-time on Jan. 24, which hopefully means his fellow Jo bros will be making an appearance on opening night. You know that old saying we just made up: Bros before shows!
