No one can claim Demi Lovato doesn't work hard for her money!
Sure, she's already a household name with fans who are going to snatch up her album like crazy, but she's still down for promoting her new album, Demi, the old-fashioned way.
DemDem was driving around New York City when she decided to go straight to the people to get her album sold!
And she used her gorgeous vocal cords to help out!
We only wish we had seen this live!
Ch-ch-check out her hardworking promotion style (below)!
