Wowza! We never thought we'd see the day when Demi turned her back on her fave British retailer, but this is a nice change of pace!
The chain-embellished, padded-shoulder dress was 80s in a good way, and when she hit the stage in zipped leggings and a cut-out leather jacket, she gave us some SERIOUS Lita Ford vibes.
She's a rock 'n' roll queen!
