Speaking in a surprise Twitter video, he said: "It's been a while, which I know you're very aware of. But I just wanted to give you an update about what's going on. I'm back.
"I've got new music coming in the new year that I'm really, really proud of.
"I appreciate you being so patient with me while I've done it. I have a whole new album, too."
The 'Put a Little Love on Me' hitmaker is also planning to play some shows on the festival circuit next year, because it is something he has "wanted to do forever
He added: "Something that I've wanted to do forever is festivals, and I've never really had the opportunity to do it.
So I think we will be announcing some festivals in the next couple of days and weeks and months for next year, which I'm really excited about
