Demi Lovato really packs a punch!

The hottie with a body delivers some serious blows in her new music video, "Confident." The vid is a Kill Bill-style revenge tale, also starring on-and-off-screen bad gal Michelle Rodriguez. The high-octane morsel, which bares a striking similarity to Taylor Swift's "Bad Blood," is also directed by Robert Rodriguez.
