Demi Lovato's got some hot new music, y'all!
Sunday night, the X Factor judge premiered her new single, "Heart Attack," on Ryan Seacrest's KIIS FM radio show's site. The single was supposed to premiere March 4 on the show, but she surprised her fans with an early release.
In the catchy, upbeat tune, the 20-year-old star sings (with a little help from Auto-Tune), "Puttin' my defenses up 'cause I don't wanna fall in love / If I ever did that, I think I'd have a heart attack."
Both Lovato and Seacrest tweeted a link to the single, adding, "Surprise!"
Perhaps the best lyric is: "When I don't care, I can play 'em like a Ken doll / Won't wash my hair, then make 'em bounce like a basketball." Get it, Barbie.
What do you think of Demi's new single!?
