New Music: Demi Lovato f/ Missy Elliott & Timbaland - 'All Night Long'

Missy Elliott is slowly making her return to music. With features on Katy Perry’s No. 1 single “Last Friday Night (T.G.I.F.)” and J. Cole’s debut Cole World, the hip-hop vet joins former Disney star Demi Lovato on the speaker-rattling “All Night Long,” a cut off her third album Unbroken (Sept. 20). Missy celebrates the weekend on the party anthem produced by her longtime collaborator Timbaland.

“It’s about staying up all night long and singing it to the boy that you like, and it’s flirty and fun and it’s not too grown-up, but it’s grown-up enough,” the 19-year-old singer told MTV News.
