We told you Demi Lovato is coming back full force! It seems like ages ago when the 19-year-old singer/actress spent was in rehab for a history of self-destructive behavior and an eating disorder. Since then, Lovato’s stardom has soared with “Skyscraper” – the first single off of her upcoming album, Unbroken (out Sept. 20).
Now, she's sharing “All Night Long,” after she teamed up with heavyweights Missy Elliot and producer Timbaland. We’re sure this one will be bumping in the club soon enough – all night long.
