Demi Lovato has returned to spotlight with feisty new single "Sorry Not Sorry".
In a post thanking her fans for their support, Lovato introduced the song.
"This is an anthem for anyone who's ever been hated on and has risen above it and come out from the other side like a savage," she wrote.
Last October, the singer announced she was taking a break without providing any suggestion of the length of her time away.
"So excited for 2017. Taking a break from music and the spotlight... I am not meant for this business and the media," she had written.
