Demi Lovato transforms into an action star for her new "Confident" video. Directed by Robert Rodriguez, the clip features Demi in fighting mode not once, but twice. (The former Disney Channel star is all "I'll kick your ass" now, don't forget.) The first time is when she gets pardoned and released from jail, to realize that she had been set up—and the second time is when she seeks revenge. Both action sequences feature Fast and Furious star Michelle Rodriguez, with Lost's Jeff Fahey closely watching.

Watch Demi Lovato's "Confident" video over at the Marriott Rewards official site (well, sure). Below, see her live rendition of new ballad "Stone Cold," released yesterday.
