The Disneyfied tween queen proved more popular than former American Idol stars Chris Daughtry and Jordin Sparks, debuting at No. 1. It's the first chart-topper for Lovato, whose rookie release, Don't Forget, opened at No. 2.
Speaking of No. 2, that's where Daughtry's Leave This Town is parked this week. Sparks's Battlefield, meanwhile, checked in at No. 7.
The number crunchers at Nielsen SoundScan report that Lovato's latest sold 107,000 to Daughtry's 100,000 last week, while Sparks' sophomore effort tallied 48,000.
Meanwhile, on the Catalog chart, Michael Jackson continues to rule. The King of Pop's Number Ones collection moved a week-best 151,000 units.
Overall, sales were down 9 percent compared to last week and down nearly 21 percent compared to the same week last year.
To recap, the top 10 albums on the Billboard 200 are as follows:
