Demi Lovato notched the second-biggest debut on the Billboard 200 this week when "Unbroken," her third album, started at No. 4 with 96,000 copies sold, according to Nielsen SoundScan. Although Lovato has frequented the Top 5 of the albums chart before -- 2009's "Don't Forget" debuted at No. 2, while "Here We Go Again" topped the chart in 2009 -- the 19-year-old singer tells Billboard.com that the debut of "Unbroken," her first album since checking into a treatment center last fall, represents a special achievement for her.
"This one is a little different," says Lovato, who dropped out of a Jonas Brothers tour in 2010 to overcome an eating disorder and self-injury issues. "I took a long time on this album, and I've been on such a journey over the past year that it just feels awesome to be able to release music that I've worked really hard on, and now that it's done well [on the chart] it feels even better."
