When Demi Lovato came to our offices last week to record a Top 20 Live set, she not only surprised us with a Lil Wayne cover, but also proved extremely genial. “Hey guys, thanks for having me! I’m Demi. What’s your name?” she introduced herself, before kicking her set off with the medley, above, of “Catch Me,” a deep cut from 2009’s Here We Go Again, and “Don’t Forget,” the title track from her 2008 debut. That same temperament shines through in the series of photographs our own Jen Marigliano snapped for our Music Seen feature, as she followed Lovato during her day in New York City. After the jump, look behind the scenes at VH1’s Top 20 and check out the elements of Lovato’s bohemian-chic style, and be sure to check back for the rest of her Top 20 Live set.
