Demi Lovato

Demi Lovato was charming and embraced her power as an artist, activist and 'X Factor' judge on 'Live With Kelly and Michael.' And power she had: She had girls screaming and sobbing at the mere sight of her!

Demi Lovato lets Lovatics tag along with her while she picks out clothes and shares fashion secrets in her VEVO 'Stylized' video.

Demi Lovato committed an oopsie when performing her new single 'Heart Attack' on 'Good Morning America' today (April 10), flubbing the lyrics. She messed up some of the lyrics on the first verse, tripping over herself. But she rebounded quickly. It sounds like she just got a little tongue-tied.

Demi Lovato's highly stylized clip for 'Heart Attack' finds the singer going to extremes. It's also a sum of all the pre-release teasers. It's Demi with no makeup. It's Demi with smoky eyes. It's Demi with oil-slicked hands. And that's it.

Demi Lovato couldn't resist dropping a final, 15-second teaser for her 'Heart Attack' video, premiering tonight (April 9). It's the fourth of four and in it, she's windblown, with smoky eyes and a focused stare. She's also bathed in liquid latex.

Flying can be a miserable experience, thanks to cramped quarters, recirculated, stale air, crappy food and a host of other reasons, but not when you are Demi Lovato and Gwyneth Paltrow. While both ladies can likely afford first class accommodations, which make air travel decidedly more pleasant, their recent travel experience was awesome since they met and bonded on a flight they shared. Cute, rig

Demi Lovato's latest teaser for her 'Heart Attack' video is the most mysterious yet.

Demi Lovato rocks her best 'Zoolander'-inspired 'Blue Steel' look in the brief new teaser for her 'Heart Attack' video. But rest assured: She looks much more lovely and much less try-hard than Ben Stiller!

Okay, there's not much to go around here, but enjoy this nine-second look at Demi Lovato's video for 'Heart Attack,' which drops April 9 ... if it doesn't leak before then, as these things tend to do.

Demi Lovato is a natural beauty. The 'X Factor' judge / 'Heart Attack' singer took to Twitter to post a makeup-free photo and encouraged her beloved Lovatics to do the same in a concerted effort to boost their self-esteem -- and based on the reactions she garnered, it worked!

Demi Lovato is coming back with a vengeance!

While L.A. Reid and Britney Spears have bounced from the merry-go-round that is the 'X Factor' judges panel after its second, ratings-challenged season, singer Demi Lovato is sticking around.

When she's not busy hobbling around on her crutches lately, Demi Lovato is hard at work on her fourth studio album and we finally have some details on it! In a short teaser, the songstress revealed that her first single off the as-yet untitled album is called 'Heart Attack,' and it's due out March 4...

Demi Lovato has gone through some major ups and downs, but while her career is soaring, she's still focusing on her sobriety. In fact, the singer even resides in a sober living facility.

Say what you want about Demi Lovato, but the girl practices what she preaches. Example: The once deeply troubled starlet has been residing in a sober living house for the past year to cope with her issues and prevent herself from regressing.

UPDATE: According to Disney Music Group, the single is not called 'Pieces of a Heart.' It is still unknown what her next single will be called, and when it will drop! Does Demi Lovato have a new song on the way? According to a rumored tweet by MTV's Sway Calloway, Lovato's 'Pieces of a Heart' will debut on 'MTV First' on Feb. 13 at precisely 7:49PM ET.
