When she’s not skyscraping, Demi Lovato is dealing with lower-altitude issues like, for instance, How to Love.

Saturday night found the newly revitalized teen star in a corner tryna put it together (or rather, onstage at Manhattan’s Hammerstein Ballroom) by turning Weezy’s slow-jam lullaby into a first-person confessional/uplift anthem.

“I am going to cover a song right now,” she told the crowd. “It’s by a rap artist, not a rap song, and it’s on the radio right now. Do you guys know what it is?” You do, Music Mixer! Because we just told you. But watch it here, after the jump:

She wears the song pretty well as her own, and judging from her smiles, happily too — which may be as much a testament to “Love”‘s instantly singable hook as to its universal themes. (Wayne as poet laureate of the human condition: who knew?)

Readers, are you a fan of the cover? And what do you think of Lovato’s new album, Unbroken, which gets a B+ in the EW issue on stands now?
