Katy Perry is Tarzan and Jane in the 21-second video teaser for 'ROAR.'

She swings on a vine, cloaked in leopard print and a green, leafy skirt, created from the lush vegetation of the jungle. She is surrounded by tigers, elephants and other creatures, exerting domain and presiding over the animal kingdom.

It's just 20 seconds of footage, but we think we're in for a real treat when Perry drops the full 'ROAR' video. She is a champion and the (killer) queen of the jungle.
