This is Demi Lovato’s second appearance on the list. Back in 2013 she in no uncertain terms announced to the world that the Disney days were long behind her. If you didn’t believe it, her hit album Unbroken, a best-selling book “Staying Strong: 365 Days a Year” and stint as a judge on The X Factor told you so. 2015 saw the Latina singer and actress cement that grown up status. Lovato’s fifth album, Confident, was released debuting at number two on the Billboard 200 and spawning the summer anthem “Cool for the Summer”, followed up by the hit single “Confident.” 2015, also saw the artist start her own record label, Safehouse Records, sign with the major modeling agency, Wilhelmina Models and nab a recurring role on the El Rey Network series From Dusk Till Dawn. Lovato shows no signs of slowing down in 2016, as she just announced plans for a tour, co-headlining with Nick Jonas.
