Listen: Demi Lovato releases new single 'Sorry Not Sorry'

Planning to release her sixth full-length album later this year, the singer dropped a new single 'Sorry Not Sorry' which is a revenge song about the people who have wronged her in the past.

Talking with Billboard about her upcoming album, Lovato said it will be "more soulful with R&B touches".

The mid-tempo tune is a fierce girl-power anthem, with the chorus, "Payback is a bad bitch/And baby I'm the baddest/You fuckin with a savage/Baby, I'm sorry (I'm not sorry)."
