Demi Lovato has been in business since she was 10 years old. The songstress, now 25, first dipped her toe in the entertainment waters with a stint on Barney & Friends (where she met BFF Selena Gomez), and her mega-singing and acting career has been skyrocketing ever since. Last year, she expanded to fashion, teaming with Kate Hudson’s activewear brand, Fabletics, adding designer to her resume. Along the way, she’s learned a thing or two about making sure there’s money in her bank account.
