To use her own words, Demi Lovato has come back from very public "breakdown, a meltdown."

Lovato will appear on "Ellen" Tuesday (Sept. 20) to promote her upcoming "Unbroken" album as well as talk frankly about her time in rehab.

"[If I] had never gone into the treatment...I don't know if one, I'd even be sitting here today. Two, if I'd be alive today."

The singer/actress has openly struggled with a past eating disorder but now hopes to provide a positive image for young girls to emulate.

"...I want to be that for a 13-year-old girl at home deciding whether or not to eat dinner or an 18-year-old deciding whether or not to keep her breakfast down...There needs to be a role model out there and for the first time in my life I actually feel like one."

Lovato is experiencing a big career resurgence; in fact, she's never been hotter. It just goes to show you that Hollywood loves a comeback just as much as it loves to see its stars head to rehab.
