During a live chat on Cambio, the singer-actress announced that her third studio record will be released on September 20, 2011.
Lovato said: "It's definitely more pop, it's not the pop-rock feel anymore. I'm showcasing my vocals a lot more like I did on [my new single] 'Skyscraper' and feeling really comfortable with what we have so far."
Lovato's younger sister Madison, who appears on Desperate Housewives, added: "I think it's the coolest album I've ever heard!"
Former Sonny with a Chance star Lovato released new track 'Skyscraper' this month. The accompanying music video features the teenager dressed in white and standing alone in the desert.
She told fans on the live chat that she has yet to decide on a follow-up single, saying: "I've actually recorded about 20-something songs. We have to cut it down to fit the album and then we'll choose the next single. I don't know which one it will be."
Lovato also hinted that a future tour could be in the works when one fan asked about her plans to hit the road.
"If I was to tour I would announce it soon," she teased. "Maybe possibly I'm in the works of putting together a tour and maybe it would be all around the world. I don't know... I'm just saying!"
Lovato released her debut album Don't Forget in 2008. It was followed by sophomore record Here We Go Again the following year.
